MQB Webasto or Eberspächer parking heater retrofit

2026-02-08T11:22:18Z

Mr-fix:

Tutorial made while retrofitting Webasto into Audi S3 8V, which shouldn't be supported.

Webasto has two main functions:
* Parking heater (warm up the cabin before starting the engine)
* Auxiliary heater (help warm up the engine faster while engine is working)

It can also be used to ventilate the car when it's hot. Not sure if the logic behind this feature is in the heater module or in Climatronic itself.

<ref>https://www.drive2.ru/l/549625247955944714/</ref>

== Schematics ==
[[File:Audi-A3-8V-WEBASTO-schematics.png|thumb]]

Webasto aux heater system contains couple elements:
* Webasto heater unit with water circulation pump, exhaust, and intake
* fuel dosing pump with fuel lines
* water hoses
* wiring harness
* remote start receiver with antenna
* remote control

Webasto unit communicates with related modules like infotainment unit (Audi MMI, VW Discover, Seat Navi...), HVAC (Climatronic). It will also checks ambient temperature, car battery charge, and car fuel level, ambient temperature.

== Parts ==
[[File:Audi-a3-8v-webasto-retrofit-kit.png|thumb|alt=Audi A3 8V webasto retrofit OEM kit|Audi A3 8V webasto retrofit OEM kit]]

Retrofit kit for Audi A3 8V is available as a whole set of needed parts and accessories:
* <code>8V0-054-960-E</code> - TDI, front-wheel drive (PR-1X0)
* <code>8V0-054-960-D</code> - TDI, all-wheel drive (PR-1X1)
* <code>8V0-054-965-C</code> - 2.0 TFSI, front-wheel drive (PR-1X0)
* <code>8V0-054-965-D</code> - 2.0 TFSI, all-wheel drive (PR-1X1)
* <code>8V0-054-965-E</code> - 1.0, 1.4, 1.5 TFSI, front-wheel drive (PR-1X0)

I can't see an option for 1.8 TFSI, but I assume that it will be the same as for 2.0 TFSI, since both engines are from [[EA888.3]] family and share most of the components.

[[File:Audi-S3-8V-extra-radiator.png|thumb|alt=Audi S3 (8V) 2.0TFSI extra radiator on the right side|Audi S3 (8V) 2.0TFSI extra radiator on the right side]]

Note: no option for Audi S3 and Audi RS3. The radiator on the right side is taking the space that normally would be available for the Webasto unit. Also the washer fluid reservoir is relocated to the right side of the vehicle, which obstructs the path for water hoses. In case of Audi RS3, you have some room in the engine bay, because the 12V battery is relocated to the trunk. In case of Audi S3, you can use an aftermarket cold-air intake system for your engine, and use some of the space from the OEM air box to fit the Webasto unit. Other option is to remove the upper part of the washer fluid reservoir (it splits into two parts) and install the Webasto unit there.

=== Webasto Heater ===
There are two versions of the Webasto Thermo Top Evo heater unit:
* Diesel (Thermo Top Evo D)
* Petrol (Thermo Top Evo B)

=== Telestart Module ===
* <code>4H0-963-271-E</code> - Audi Telestart module by Eberspächer.

=== Antenna ===
There's a fakra connector on the Telestart module. If Audi A3 is factory fitted with Webasto, module is connected with the roof antenna module. For retrofit there's an additional antenna that you can stick to the cars body.

Cheap generic antenna from AliExpress works just fine. If there's a change of accessing bottom the OEM roof antenna, I would love to wire the module to it. I believe the roof antenna will provide better signal and higher remote range.

=== Remote ===
There's couple of remotes that you can use. Of course Audi/Porsche/Bentley has the coolest one, with the display and more options. Other remotes (VW, Skoda, Seat...) are simpler, with just two buttons, no display, and status indicator LED.
* <code>4N0-963-511</code> - Audi, two buttons
* <code>4H0-963-511-A/B</code> - Audi, 4 buttons, red backlight ([[Eberspächer EasyStart R+]])
* <code>4H0-963-511-C/D</code> - Audi, 4 buttons, white backlight ([[Eberspächer EasyStart R+]]) by Eberspächer
* <code>3G0-963-511-D</code> - VW, two buttons
* <code>7N0-963-511-B</code> - VW, two buttons (T91R)
* <code>8K0-963-511 / 7E0-963-511-B</code> - Audi, two buttons

=== Wiring kit ===
I've got one of those, new:
* <code>8V0-054-931</code> - wiring installation kit for Audi A3 8V. ([[8V0-054-931]])
Paid ~€50 for it. And it contains a lot of little things that I believe will be necessary during the installation.

=== Fuel pump and fuel line ===
OEM fuel tank pump assembly is prepared to connect additional line to it. Also the fuel tank is equipped with a small hanger on the side to install the webasto fuel pump.

Fuel line needs to be guided through, all the way to the engine bay.

=== Coolant pipes ===
If installing in unsupported vehicle, you will need a generic silicone hose, 20mm inner diameter.

== Installation ==
OEM installation tutorial ''was'' available to download:
* https://pim.audi.com/pdf/EBA/EBA_8V0054960B_pl_190315.pdf
* https://pim.audi.com/pdf/EBA/EBA_8V0054960B_en_190315.pdf

When it comes to fitting Webasto unit into Audi S3, I had to remove the units exhaust, units intake, circulation pump, and both mounting brackets. Webasto unit alone has a compact shape and fits under the OEM air filter box. It will also require to use an universal exhaust once the unit is mounted and some modifications for fuel line and wiring.

Note: no option for Audi S3 and Audi RS3.

I can't see an option for 1.8 TFSI, but I assume that it will be the same as for 2.0 TFSI, since both engines are from [[EA888.3]] family and share a lot of components.

=== Webasto Heater ===
[[File:Audi-S3-8V-extra-radiator.png|thumb|alt=Audi S3 (8V) 2.0TFSI extra radiator on the right side|Audi S3 (8V) 2.0TFSI extra radiator on the right side]]

There are two versions of the Webasto Thermo Top Evo heater unit:
* Diesel (Thermo Top Evo D)
* Petrol (Thermo Top Evo B)

=== Telestart Module ===
* <code>4H0-963-271-E</code> - Audi Telestart module by Eberspächer.

=== Antenna ===
There's a fakra connector on the Telestart module. If Audi A3 is factory fitted with Webasto, module is connected with the roof antenna module. For retrofit there's an additional antenna that you can stick to the cars body.

I will also try to use a generic antenna from AliExpress, just to see if I can pair the remote with it. If there's a change of accessing bottom the OEM roof antenna, I would love to wire the module to it. I believe the roof antenna will provide better signal and higher remote range.

=== Remote ===
There's couple of remotes that you can use. Of course Audi has the coolest one, with the display. But I believe other remotes (VW, Skoda...) should also work, since the heater module is the same for those cars.

=== Wiring kit ===
I've got one of those, new:
* <code>8V0-054-931</code> - wiring installation kit for Audi A3 8V. ([[8V0-054-931]])
Paid ~€50 for it. And it contains a lot of little things that I believe will be necessary during the installation.

=== Fuel lines and pump ===
=== Coolant pipes ===

There's no official tutorial nor parts for Audi S3 and Audi RS3. Most likely this is caused by the two additional radiators and other changes in those high-power variants.

The radiator on the right side is taking the space that normally would be available for the Webasto unit. Also the washer fluid reservoir is relocated to the right side of the vehicle, which obstructs the path for water hoses.

In case of Audi RS3, you have some room in the engine bay, because the 12V battery is relocated to the trunk.

In case of Audi S3, you can use an aftermarket cold-air intake system for your engine, and use some of the space from the OEM air box to fit the Webasto unit. Other option is to remove the upper part of the washer fluid reservoir (it splits into two parts) and install the Webasto unit there.

When it comes to fitting Webasto unit into Audi S3, I had to remove the units exhaust, units intake, circulation pump, and both mounting brackets. Webasto unit alone has a compact shape and will most likely fit under the OEM air filter box. It will also require to use an universal exhaust once the unit is mounted and some modifications for fuel line and wiring.

Aux Heater Ventilation activation in Audi

2026-02-01T18:16:05Z

Mr-fix: /* Telestart */

Some VAG vehicles (for example Audi Q7 4L) with some engines (for example 4.2TDI) are equipped with aux. heater from the factory. There's no remote start module (Webasto Telestart). The aux heater is controlled by the engine or climatronic module and used as a supplementary coolant heater. It turns on automatically with a cold engine. But you can add timer controls to it!

== Coding for Webasto Timer support ==
<code>Module 08 → Long Coding → byte 02 → bit 3 → enable</code>
Above coding example is for Audi Q7 4L (2014, after facelift, with 4-Zone Climatronic System).

Also make sure that the aux heater options are set in MMI → Green Engineering Menu → car.

== Adaptation of the Webasto logic ==
<code>Module 08 → Adaptation → Channel: 3 (Aux Heater Continues To Run after Engine Turned Of) → 1(yes)/2(no)</code>

<code>Module 08 → Adaptation → Channel: 15 (Fan Speed in Aux Heating Mode) → 60</code><ref>https://www.audiforum.us/threads/parking-auxiliary-heater.11422/page-7?post_id=76799#post-76799</ref>

<code>Module 08 → Adaptation → Channel: 16 (Aux Heater in Residual Heating Mode) → 0(off)/1(on)</code>

<code>Module 08 → Adaptation → Channel: 19 (Aux Heater Available in ECON Mode) → 0(off)/1(on)</code>

== Telestart ==
Adding telestart module (with wiring, antenna, and remote) will add functionality to turn on parking heater remotely.<ref>https://www.drive2.ru/l/554764915059983709/</ref>

=== Module ===

Tutorial made while retrofitting Webasto into Audi S3 8V, which shouldn't be supported.

Webasto has two main functions:
* Parking heater (warm up the engine and cabin before starting the engine)

It can also be used to ventilate the car when it's hot. Not sure if the logic behind this feature is in the heater module or in Climatronic itself.

It will also require to use an universal exhaust once the unit is mounted and some modifications for fuel line and wiring.

MQB Webasto or Eberspächer parking heater retrofit

2026-02-01T16:57:17Z

Mr-fix: /* Basic Settings */

Tutorial made while retrofitting Webasto into Audi S3 8V, which shouldn't be supported.

Webasto has two main functions:
* Parking heater (warm up the engine and cabin before starting the engine)
* Auxiliary heater (help warm up the engine faster while engine is working)

It can also be used to ventilate the car when it's hot. Not sure if the logic behind this feature is in the heater module or in Climatronic itself.

== Schematics ==
[[File:Audi-A3-8V-WEBASTO-schematics.png|thumb]]

Webasto aux heater system contains couple elements:
* Webasto heater unit with water circulation pump, exhaust, and intake
* fuel dosing pump with fuel lines
* water hoses
* wiring harness
* remote start receiver with antenna
* remote control

Webasto unit communicates with related modules like infotainment unit (Audi MMI, VW Discover, Seat Navi...) and HVAC (Climatronic). It will also check ambient temperature, car battery charge, and car fuel level.

== Parts ==
[[File:Audi-a3-8v-webasto-retrofit-kit.png|thumb|alt=Audi A3 8V webasto retrofit OEM kit|Audi A3 8V webasto retrofit OEM kit]]

Retrofit kit for Audi A3 8V is available as a whole set of needed parts and accessories:
* <code>8V0-054-960-E</code> - TDI, front-wheel drive (PR-1X0)
* <code>8V0-054-960-D</code> - TDI, all-wheel drive (PR-1X1)
* <code>8V0-054-965-C</code> - 2.0 TFSI, front-wheel drive (PR-1X0)
* <code>8V0-054-965-D</code> - 2.0 TFSI, all-wheel drive (PR-1X1)
* <code>8V0-054-965-E</code> - 1.0, 1.4, 1.5 TFSI, front-wheel drive (PR-1X0)

Note: no option for Audi S3 and Audi RS3.

I can't see an option for 1.8 TFSI, but I assume that it will be the same as for 2.0 TFSI, since both engines are from [[EA888.3]] family and share a lot of components.

=== Webasto Heater ===
[[File:Audi-S3-8V-extra-radiator.png|thumb|alt=Audi S3 (8V) 2.0TFSI extra radiator on the right side|Audi S3 (8V) 2.0TFSI extra radiator on the right side]]

There are two versions of the Webasto Thermo Top Evo heater unit:
* Diesel (Thermo Top Evo D)
* Petrol (Thermo Top Evo B)

=== Telestart Module ===
* <code>4H0-963-271-E</code> - Audi Telestart module by Eberspächer.

=== Antenna ===
There's a fakra connector on the Telestart module. If Audi A3 is factory fitted with Webasto, module is connected with the roof antenna module. For retrofit there's an additional antenna that you can stick to the cars body.

I will also try to use a generic antenna from AliExpress, just to see if I can pair the remote with it. If there's a change of accessing bottom the OEM roof antenna, I would love to wire the module to it. I believe the roof antenna will provide better signal and higher remote range.

=== Remote ===
There's couple of remotes that you can use. Of course Audi has the coolest one, with the display. But I believe other remotes (VW, Skoda...) should also work, since the heater module is the same for those cars.
* <code>4N0-963-511</code> - Audi, two buttons
* <code>4H0-963-511-A/B</code> - Audi, 4 buttons, red backlight ([[Eberspächer EasyStart R+]])
* <code>4H0-963-511-C/D</code> - Audi, 4 buttons, white backlight ([[Eberspächer EasyStart R+]]) by Eberspächer
* <code>3G0-963-511-D</code> - VW, two buttons
* <code>7N0-963-511-B</code> - VW, two buttons (T91R)
* <code>8K0-963-511 / 7E0-963-511-B</code> - Audi, two buttons

=== Wiring kit ===
I've got one of those, new:
* <code>8V0-054-931</code> - wiring installation kit for Audi A3 8V. ([[8V0-054-931]])
Paid ~€50 for it. And it contains a lot of little things that I believe will be necessary during the installation.

=== Fuel lines and pump ===
=== Coolant pipes ===

== Installation ==
OEM installation tutorial ''was'' available to download:
* https://pim.audi.com/pdf/EBA/EBA_8V0054960B_pl_190315.pdf
* https://pim.audi.com/pdf/EBA/EBA_8V0054960B_en_190315.pdf

There's no official tutorial nor parts for Audi S3 and Audi RS3. Most likely this is caused by the two additional radiators and other changes in those high-power variants.

The radiator on the right side is taking the space that normally would be available for the Webasto unit. Also the washer fluid reservoir is relocated to the right side of the vehicle, which obstructs the path for water hoses.

In case of Audi RS3, you have some room in the engine bay, because the 12V battery is relocated to the trunk.

In case of Audi S3, you can use an aftermarket cold-air intake system for your engine, and use some of the space from the OEM air box to fit the Webasto unit. Other option is to remove the upper part of the washer fluid reservoir (it splits into two parts) and install the Webasto unit there.

When it comes to fitting Webasto unit into Audi S3, I had to remove the units exhaust, units intake, circulation pump, and both mounting brackets. Webasto unit alone has a compact shape and will most likely fit under the OEM air filter box. It will also require to use an universal exhaust once the unit is mounted and some modifications for fuel line and wiring.

There's couple of remotes that you can use. Of course Audi has the coolest one, with the display. But I believe other remotes (VW, Skoda...) should also work, since the heater module is the same for those cars.

There's no official tutorial nor parts for Audi S3 and Audi RS3. Most likely this is caused by the two additional radiators and other changes in those high-power variants.

The radiator on the right side is taking the space that normally would be available for the Webasto unit. Also the washer fluid reservoir is relocated to the right side of the vehicle, which obstructs the path for water hoses.

In case of Audi RS3, you have some room in the engine bay, because the 12V battery is relocated to the trunk.

In case of Audi S3, you can use an aftermarket cold-air intake system for your engine, and use some of the space from the OEM air box to fit the Webasto unit. Other option is to remove the upper part of the washer fluid reservoir (it splits into two parts) and install the Webasto unit there.

When it comes to fitting Webasto unit into Audi S3, I had to remove the units exhaust, units intake, circulation pump, and both mounting brackets. Webasto unit alone has a compact shape and will most likely fit under the OEM air filter box. It will also require to use an universal exhaust once the unit is mounted and some modifications for fuel line and wiring.

MQB Webasto or Eberspächer parking heater retrofit

2026-02-01T16:29:45Z

Mr-fix: /* Coding & Adaptation */

Tutorial made while retrofitting Webasto into Audi S3 8V, which shouldn't be supported.

Webasto has two main functions:
* Parking heater (warm up the engine and cabin before starting the engine)
* Auxiliary heater (help warm up the engine faster while engine is working)

It can also be used to ventilate the car when it's hot. Not sure if the logic behind this feature is in the heater module or in Climatronic itself.

== Schematics ==
[[File:Audi-A3-8V-WEBASTO-schematics.png|thumb]]

Webasto aux heater system contains couple elements:
* Webasto heater unit with water circulation pump, exhaust, and intake
* fuel dosing pump with fuel lines
* water hoses
* wiring harness
* remote start receiver with antenna
* remote control

Webasto unit communicates with related modules like infotainment unit (Audi MMI, VW Discover, Seat Navi...) and HVAC (Climatronic). It will also check ambient temperature, car battery charge, and car fuel level.

== Parts ==
[[File:Audi-a3-8v-webasto-retrofit-kit.png|thumb|alt=Audi A3 8V webasto retrofit OEM kit|Audi A3 8V webasto retrofit OEM kit]]

Retrofit kit for Audi A3 8V is available as a whole set of needed parts and accessories:
* <code>8V0-054-960-E</code> - TDI, front-wheel drive (PR-1X0)
* <code>8V0-054-960-D</code> - TDI, all-wheel drive (PR-1X1)
* <code>8V0-054-965-C</code> - 2.0 TFSI, front-wheel drive (PR-1X0)
* <code>8V0-054-965-D</code> - 2.0 TFSI, all-wheel drive (PR-1X1)
* <code>8V0-054-965-E</code> - 1.0, 1.4, 1.5 TFSI, front-wheel drive (PR-1X0)

Note: no option for Audi S3 and Audi RS3.

I can't see an option for 1.8 TFSI, but I assume that it will be the same as for 2.0 TFSI, since both engines are from [[EA888.3]] family and share a lot of components.

=== Webasto Heater ===

There are two versions of the Webasto Thermo Top Evo heater unit:
* Diesel (Thermo Top Evo D)
* Petrol (Thermo Top Evo B)

=== Telestart Module ===
* <code>4H0-963-271-E</code> - Audi Telestart module by Eberspächer.

=== Antenna ===
There's a fakra connector on the Telestart module. If Audi A3 is factory fitted with Webasto, module is connected with the roof antenna module. For retrofit there's an additional antenna that you can stick to the cars body.

I will also try to use a generic antenna from AliExpress, just to see if I can pair the remote with it. If there's a change of accessing bottom the OEM roof antenna, I would love to wire the module to it. I believe the roof antenna will provide better signal and higher remote range.

There's a fakra connector on the Telestart module. If Audi A3 is factory fitted with Webasto, module is connected with the roof antenna module. For retrofit there's an additional antenna that you can stick to the cars body.

I will also try to use a generic antenna from AliExpress, just to see if I can pair the remote with it. If there's a change of accessing bottom the OEM roof antenna, I would love to wire the module to it. I believe the roof antenna will provide better signal and higher remote range.

=== Remote ===
There's couple of remotes that you can use. Of course Audi has the coolest one, with the display. But I believe other remotes (VW, Skoda...) should also work, since the heater module is the same for those cars.

There's no official tutorial nor parts for Audi S3 and Audi RS3. Most likely this is caused by the two additional radiators and other changes in those high-power variants.

The radiator on the right side is taking the space that normally would be available for the Webasto unit. Also the washer fluid reservoir is relocated to the right side of the vehicle, which obstructs the path for water hoses.

In case of Audi RS3, you have some room in the engine bay, because the 12V battery is relocated to the trunk.

In case of Audi S3, you can use an aftermarket cold-air intake system for your engine, and use some of the space from the OEM air box to fit the Webasto unit. Other option is to remove the upper part of the washer fluid reservoir (it splits into two parts) and install the Webasto unit there.

When it comes to fitting Webasto unit into Audi S3, I had to remove the units exhaust, units intake, circulation pump, and both mounting brackets. Webasto unit alone has a compact shape and will most likely fit under the OEM air filter box. It will also require to use an universal exhaust once the unit is mounted and some modifications for fuel line and wiring.

MQB Webasto or Eberspächer parking heater retrofit

Mr-fix: Mr-fix moved page Webasto or Eberspächer retrofit to MQB Webasto or Eberspächer parking heater retrofit: better title

Tutorial made while retrofitting Webasto into Audi S3 8V, which shouldn't be supported.

Webasto has two main functions:
* Parking heater (warm up the engine and cabin before starting the engine)
* Auxiliary heater (help warm up the engine faster while engine is working)

It can also be used to ventilate the car when it's hot. Not sure if the logic behind this feature is in the heater module or in Climatronic itself.

[[File:Audi-A3-8V-WEBASTO-schematics.png|thumb]]

Webasto aux heater system contains couple elements:
* Webasto heater unit with water circulation pump, exhaust, and intake
* fuel dosing pump with fuel lines
* water hoses
* wiring harness
* remote start receiver with antenna
* remote control

Webasto unit communicates with related modules like infotainment unit (Audi MMI, VW Discover, Seat Navi...) and HVAC (Climatronic). It will also check ambient temperature, car battery charge, and car fuel level.

[[File:Audi-a3-8v-webasto-retrofit-kit.png|thumb|alt=Audi A3 8V webasto retrofit OEM kit|Audi A3 8V webasto retrofit OEM kit]]

Retrofit kit for Audi A3 8V is available as a whole set of needed parts and accessories:
* <code>8V0-054-960-E</code> - TDI, front-wheel drive (PR-1X0)
* <code>8V0-054-960-D</code> - TDI, all-wheel drive (PR-1X1)

There's no official tutorial nor parts for Audi S3 and Audi RS3. Most likely this is caused by the two additional radiators and other changes in those high-power variants.

The radiator on the right side is taking the space that normally would be available for the Webasto unit. Also the washer fluid reservoir is relocated to the right side of the vehicle, which obstructs the path for water hoses.

In case of Audi RS3, you have some room in the engine bay, because the 12V battery is relocated to the trunk.

In case of Audi S3, you can use an aftermarket cold-air intake system for your engine, and use some of the space from the OEM air box to fit the Webasto unit. Other option is to remove the upper part of the washer fluid reservoir (it splits into two parts) and install the Webasto unit there.

When it comes to fitting Webasto unit into Audi S3, I had to remove the units exhaust, units intake, circulation pump, and both mounting brackets. Webasto unit alone has a compact shape and will most likely fit under the OEM air filter box. It will also require to use an universal exhaust once the unit is mounted and some modifications for fuel line and wiring.

MQB Webasto or Eberspächer parking heater retrofit

2026-01-18T17:00:05Z

Mr-fix: /* Coding & Adaptation */

Tutorial made while retrofitting Webasto into Audi S3 8V, which shouldn't be supported.

Webasto has two main functions:
* Parking heater (warm up the engine and cabin before starting the engine)
* Auxiliary heater (help warm up the engine faster while engine is working)

It can also be used to ventilate the car when it's hot. Not sure if the logic behind this feature is in the heater module or in Climatronic itself.

== Schematics ==
[[File:Audi-A3-8V-WEBASTO-schematics.png|thumb]]

Webasto aux heater system contains couple elements:
* Webasto heater unit with water circulation pump, exhaust, and intake
* fuel dosing pump with fuel lines
* water hoses
* wiring harness
* remote start receiver with antenna
* remote control

Webasto unit communicates with related modules like infotainment unit (Audi MMI, VW Discover, Seat Navi...) and HVAC (Climatronic). It will also check ambient temperature, car battery charge, and car fuel level.

== Parts ==
[[File:Audi-a3-8v-webasto-retrofit-kit.png|thumb|alt=Audi A3 8V webasto retrofit OEM kit|Audi A3 8V webasto retrofit OEM kit]]

Retrofit kit for Audi A3 8V is available as a whole set of needed parts and accessories:
* <code>8V0-054-960-E</code> - TDI, front-wheel drive (PR-1X0)
* <code>8V0-054-960-D</code> - TDI, all-wheel drive (PR-1X1)
* <code>8V0-054-965-C</code> - 2.0 TFSI, front-wheel drive (PR-1X0)
* <code>8V0-054-965-D</code> - 2.0 TFSI, all-wheel drive (PR-1X1)
* <code>8V0-054-965-E</code> - 1.0, 1.4, 1.5 TFSI, front-wheel drive (PR-1X0)

Note: no option for Audi S3 and Audi RS3.

I can't see an option for 1.8 TFSI, but I assume that it will be the same as for 2.0 TFSI, since both engines are from [[EA888.3]] family and share a lot of components.

=== Webasto Heater ===
[[File:Audi-S3-8V-extra-radiator.png|thumb|alt=Audi S3 (8V) 2.0TFSI extra radiator on the right side|Audi S3 (8V) 2.0TFSI extra radiator on the right side]]

There are two versions of the Webasto Thermo Top Evo heater unit:
* Diesel (Thermo Top Evo D)
* Petrol (Thermo Top Evo B)

=== Telestart Module ===
* <code>4H0-963-271-E</code> - Audi Telestart module by Eberspächer.

=== Antenna ===
There's a fakra connector on the Telestart module. If Audi A3 is factory fitted with Webasto, module is connected with the roof antenna module. For retrofit there's an additional antenna that you can stick to the cars body.

I will also try to use a generic antenna from AliExpress, just to see if I can pair the remote with it. If there's a change of accessing bottom the OEM roof antenna, I would love to wire the module to it. I believe the roof antenna will provide better signal and higher remote range.

=== Remote ===
There's couple of remotes that you can use. Of course Audi has the coolest one, with the display. But I believe other remotes (VW, Skoda...) should also work, since the heater module is the same for those cars.
* <code>4N0-963-511</code> - Audi, two buttons
* <code>4H0-963-511-A/B</code> - Audi, 4 buttons, red backlight ([[Eberspächer EasyStart R+]])
* <code>4H0-963-511-C/D</code> - Audi, 4 buttons, white backlight ([[Eberspächer EasyStart R+]]) by Eberspächer
* <code>3G0-963-511-D</code> - VW, two buttons
* <code>7N0-963-511-B</code> - VW, two buttons (T91R)
* <code>8K0-963-511 / 7E0-963-511-B</code> - Audi, two buttons

=== Wiring kit ===
I've got one of those, new:
* <code>8V0-054-931</code> - wiring installation kit for Audi A3 8V. ([[8V0-054-931]])
Paid ~€50 for it. And it contains a lot of little things that I believe will be necessary during the installation.

=== Fuel lines and pump ===
=== Coolant pipes ===

MQB Webasto or Eberspächer parking heater retrofit

2026-01-18T16:48:20Z

Mr-fix: /* Gateway */

Tutorial made while retrofitting Webasto into Audi S3 8V, which shouldn't be supported.

Webasto has two main functions:
* Parking heater (warm up the engine and cabin before starting the engine)
* Auxiliary heater (help warm up the engine faster while engine is working)

It can also be used to ventilate the car when it's hot. Not sure if the logic behind this feature is in the heater module or in Climatronic itself.

Webasto aux heater system contains couple elements:
* Webasto heater unit with water circulation pump, exhaust, and intake
* fuel dosing pump with fuel lines
* water hoses
* wiring harness
* remote start receiver with antenna
* remote control

Webasto unit communicates with related modules like infotainment unit (Audi MMI, VW Discover, Seat Navi...) and HVAC (Climatronic). It will also check ambient temperature, car battery charge, and car fuel level.

Retrofit kit for Audi A3 8V is available as a whole set of needed parts and accessories:
* <code>8V0-054-960-E</code> - TDI, front-wheel drive (PR-1X0)
* <code>8V0-054-960-D</code> - TDI, all-wheel drive (PR-1X1)

* <code>8V0-054-965-E</code> - 1.0, 1.4, 1.5 TFSI, front-wheel drive (PR-1X0)

Note: no option for Audi S3 and Audi RS3.

I can't see an option for 1.8 TFSI, but I assume that it will be the same as for 2.0 TFSI, since both engines are from [[EA888.3]] family and share a lot of components.

There are two versions of the Webasto Thermo Top Evo heater unit:
* Diesel (Thermo Top Evo D)
* Petrol (Thermo Top Evo B)

=== Telestart Module ===

=== Antenna ===
There's a fakra connector on the Telestart module. If Audi A3 is factory fitted with Webasto, module is connected with the roof antenna module. For retrofit there's an additional antenna that you can stick to the cars body.

I will also try to use a generic antenna from AliExpress, just to see if I can pair the remote with it. If there's a change of accessing bottom the OEM roof antenna, I would love to wire the module to it. I believe the roof antenna will provide better signal and higher remote range.

=== Remote ===
There's couple of remotes that you can use. Of course Audi has the coolest one, with the display. But I believe other remotes (VW, Skoda...) should also work, since the heater module is the same for those cars.

There's no official tutorial nor parts for Audi S3 and Audi RS3. Most likely this is caused by the two additional radiators and other changes in those high-power variants.

The radiator on the right side is taking the space that normally would be available for the Webasto unit. Also the washer fluid reservoir is relocated to the right side of the vehicle, which obstructs the path for water hoses.

In case of Audi RS3, you have some room in the engine bay, because the 12V battery is relocated to the trunk.

In case of Audi S3, you can use an aftermarket cold-air intake system for your engine, and use some of the space from the OEM air box to fit the Webasto unit. Other option is to remove the upper part of the washer fluid reservoir (it splits into two parts) and install the Webasto unit there.

When it comes to fitting Webasto unit into Audi S3, I had to remove the units exhaust, units intake, circulation pump, and both mounting brackets. Webasto unit alone has a compact shape and will most likely fit under the OEM air filter box. It will also require to use an universal exhaust once the unit is mounted and some modifications for fuel line and wiring.

Aux Heater Ventilation activation in Audi

2026-01-16T13:43:25Z

Mr-fix: /* Telestart */

Some VAG vehicles (for example Audi Q7 4L) with some engines (for example 4.2TDI) are equipped with aux. heater from the factory. There's no remote start module (Webasto Telestart). The aux heater is controlled by the engine or climatronic module and used as a supplementary coolant heater. It turns on automatically with a cold engine. But you can add timer controls to it!

== Coding for Webasto Timer support ==
<code>Module 08 → Long Coding → byte 02 → bit 3 → enable</code>
Above coding example is for Audi Q7 4L (2014, after facelift, with 4-Zone Climatronic System).

Also make sure that the aux heater options are set in MMI → Green Engineering Menu → car.

== Adaptation of the Webasto logic ==
<code>Module 08 → Adaptation → Channel: 3 (Aux Heater Continues To Run after Engine Turned Of) → 1(yes)/2(no)</code>

<code>Module 08 → Adaptation → Channel: 15 (Fan Speed in Aux Heating Mode) → 60</code><ref>https://www.audiforum.us/threads/parking-auxiliary-heater.11422/page-7?post_id=76799#post-76799</ref>

<code>Module 08 → Adaptation → Channel: 16 (Aux Heater in Residual Heating Mode) → 0(off)/1(on)</code>

<code>Module 08 → Adaptation → Channel: 19 (Aux Heater Available in ECON Mode) → 0(off)/1(on)</code>

== Telestart ==
Adding telestart module (with wiring, antenna, and remote) will add functionality to turn on parking heater remotely.<ref>https://www.drive2.ru/l/554764915059983709/</ref>

=== Module ===

MQB Webasto or Eberspächer parking heater retrofit

2026-01-16T10:37:38Z

Mr-fix: /* Coding & Adaptation */

Tutorial made while retrofitting Webasto into Audi S3 8V, which shouldn't be supported.

Webasto has two main functions:
* Parking heater (warm up the engine and cabin before starting the engine)
* Auxiliary heater (help warm up the engine faster while engine is working)

It can also be used to ventilate the car when it's hot. Not sure if the logic behind this feature is in the heater module or in Climatronic itself.

== Schematics ==
[[File:Audi-A3-8V-WEBASTO-schematics.png|thumb]]

Webasto aux heater system contains couple elements:
* Webasto heater unit with water circulation pump, exhaust, and intake
* fuel dosing pump with fuel lines
* water hoses
* wiring harness
* remote start receiver with antenna
* remote control

Webasto unit communicates with related modules like infotainment unit (Audi MMI, VW Discover, Seat Navi...) and HVAC (Climatronic). It will also check ambient temperature, car battery charge, and car fuel level.

== Parts ==
[[File:Audi-a3-8v-webasto-retrofit-kit.png|thumb|alt=Audi A3 8V webasto retrofit OEM kit|Audi A3 8V webasto retrofit OEM kit]]

Retrofit kit for Audi A3 8V is available as a whole set of needed parts and accessories:
* <code>8V0-054-960-E</code> - TDI, front-wheel drive (PR-1X0)
* <code>8V0-054-960-D</code> - TDI, all-wheel drive (PR-1X1)
* <code>8V0-054-965-C</code> - 2.0 TFSI, front-wheel drive (PR-1X0)
* <code>8V0-054-965-D</code> - 2.0 TFSI, all-wheel drive (PR-1X1)
* <code>8V0-054-965-E</code> - 1.0, 1.4, 1.5 TFSI, front-wheel drive (PR-1X0)

Note: no option for Audi S3 and Audi RS3.

I can't see an option for 1.8 TFSI, but I assume that it will be the same as for 2.0 TFSI, since both engines are from [[EA888.3]] family and share a lot of components.

=== Webasto Heater ===
[[File:Audi-S3-8V-extra-radiator.png|thumb|alt=Audi S3 (8V) 2.0TFSI extra radiator on the right side|Audi S3 (8V) 2.0TFSI extra radiator on the right side]]

There are two versions of the Webasto Thermo Top Evo heater unit:
* Diesel (Thermo Top Evo D)
* Petrol (Thermo Top Evo B)

=== Telestart Module ===
* <code>4H0-963-271-E</code> - Audi Telestart module by Eberspächer.

=== Antenna ===
There's a fakra connector on the Telestart module. If Audi A3 is factory fitted with Webasto, module is connected with the roof antenna module. For retrofit there's an additional antenna that you can stick to the cars body.

I will also try to use a generic antenna from AliExpress, just to see if I can pair the remote with it. If there's a change of accessing bottom the OEM roof antenna, I would love to wire the module to it. I believe the roof antenna will provide better signal and higher remote range.

=== Remote ===
There's couple of remotes that you can use. Of course Audi has the coolest one, with the display. But I believe other remotes (VW, Skoda...) should also work, since the heater module is the same for those cars.
* <code>4N0-963-511</code> - Audi, two buttons
* <code>4H0-963-511-A/B</code> - Audi, 4 buttons, red backlight ([[Eberspächer EasyStart R+]])
* <code>4H0-963-511-C/D</code> - Audi, 4 buttons, white backlight ([[Eberspächer EasyStart R+]]) by Eberspächer
* <code>3G0-963-511-D</code> - VW, two buttons
* <code>7N0-963-511-B</code> - VW, two buttons (T91R)
* <code>8K0-963-511 / 7E0-963-511-B</code> - Audi, two buttons

=== Wiring kit ===
I've got one of those, new:
* <code>8V0-054-931</code> - wiring installation kit for Audi A3 8V. ([[8V0-054-931]])
Paid ~€50 for it. And it contains a lot of little things that I believe will be necessary during the installation.

=== Fuel lines and pump ===
=== Coolant pipes ===

== Installation ==

* https://pim.audi.com/pdf/EBA/EBA_8V0054960B_en_190315.pdf

There's no official tutorial nor parts for Audi S3 and Audi RS3. Most likely this is caused by the two additional radiators and other changes in those high-power variants.

The radiator on the right side is taking the space that normally would be available for the Webasto unit. Also the washer fluid reservoir is relocated to the right side of the vehicle, which obstructs the path for water hoses.

In case of Audi RS3, you have some room in the engine bay, because the 12V battery is relocated to the trunk.

In case of Audi S3, you can use an aftermarket cold-air intake system for your engine, and use some of the space from the OEM air box to fit the Webasto unit. Other option is to remove the upper part of the washer fluid reservoir (it splits into two parts) and install the Webasto unit there.

When it comes to fitting Webasto unit into Audi S3, I had to remove the units exhaust, units intake, circulation pump, and both mounting brackets. Webasto unit alone has a compact shape and will most likely fit under the OEM air filter box. It will also require to use an universal exhaust once the unit is mounted and some modifications for fuel line and wiring.

[[File:Audi-A3-8V-WEBASTO-schematics.png|thumb]]

Webasto aux heater system contains couple elements:
* Webasto heater unit with water circulation pump, exhaust, and intake
* fuel dosing pump with fuel lines
* water hoses
* wiring harness
* remote start receiver with antenna
* remote control

Webasto unit communicates with related modules like infotainment unit (Audi MMI, VW Discover, Seat Navi...) and HVAC (Climatronic). It will also check ambient temperature, car battery charge, and car fuel level.

== Parts ==
[[File:Audi-a3-8v-webasto-retrofit-kit.png|thumb|alt=Audi A3 8V webasto retrofit OEM kit|Audi A3 8V webasto retrofit OEM kit]]

Retrofit kit for Audi A3 8V is available as a whole set of needed parts and accessories:
* <code>8V0-054-960-E</code> - TDI, front-wheel drive (PR-1X0)
* <code>8V0-054-960-D</code> - TDI, all-wheel drive (PR-1X1)
* <code>8V0-054-965-C</code> - 2.0 TFSI, front-wheel drive (PR-1X0)
* <code>8V0-054-965-D</code> - 2.0 TFSI, all-wheel drive (PR-1X1)
* <code>8V0-054-965-E</code> - 1.0, 1.4, 1.5 TFSI, front-wheel drive (PR-1X0)

Note: no option for Audi S3 and Audi RS3.

I can't see an option for 1.8 TFSI, but I assume that it will be the same as for 2.0 TFSI, since both engines are from [[EA888.3]] family and share a lot of components.

=== Webasto Heater ===
[[File:Audi-S3-8V-extra-radiator.png|thumb|alt=Audi S3 (8V) 2.0TFSI extra radiator on the right side|Audi S3 (8V) 2.0TFSI extra radiator on the right side]]

There are two versions of the Webasto Thermo Top Evo heater unit:
* Diesel (Thermo Top Evo D)
* Petrol (Thermo Top Evo B)

=== Telestart Module ===
* <code>4H0-963-271-E</code> - Audi Telestart module by Eberspächer.

=== Antenna ===
There's a fakra connector on the Telestart module. If Audi A3 is factory fitted with Webasto, module is connected with the roof antenna module. For retrofit there's an additional antenna that you can stick to the cars body.

I will also try to use a generic antenna from AliExpress, just to see if I can pair the remote with it. If there's a change of accessing bottom the OEM roof antenna, I would love to wire the module to it. I believe the roof antenna will provide better signal and higher remote range.

=== Remote ===
There's couple of remotes that you can use. Of course Audi has the coolest one, with the display. But I believe other remotes (VW, Skoda...) should also work, since the heater module is the same for those cars.
* <code>4N0-963-511</code> - Audi, two buttons
* <code>4H0-963-511-A/B</code> - Audi, 4 buttons, red backlight ([[Eberspächer EasyStart R+]])
* <code>4H0-963-511-C/D</code> - Audi, 4 buttons, white backlight ([[Eberspächer EasyStart R+]]) by Eberspächer
* <code>3G0-963-511-D</code> - VW, two buttons
* <code>7N0-963-511-B</code> - VW, two buttons (T91R)
* <code>8K0-963-511 / 7E0-963-511-B</code> - Audi, two buttons

=== Wiring kit ===
I've got one of those, new:
* <code>8V0-054-931</code> - wiring installation kit for Audi A3 8V. ([[8V0-054-931]])
Paid ~€50 for it. And it contains a lot of little things that I believe will be necessary during the installation.

=== Fuel lines and pump ===
=== Coolant pipes ===

== Installation ==
OEM installation tutorial ''was'' available to download:
* https://pim.audi.com/pdf/EBA/EBA_8V0054960B_pl_190315.pdf
* https://pim.audi.com/pdf/EBA/EBA_8V0054960B_en_190315.pdf

There's no official tutorial nor parts for Audi S3 and Audi RS3. Most likely this is caused by the two additional radiators and other changes in those high-power variants.

The radiator on the right side is taking the space that normally would be available for the Webasto unit. Also the washer fluid reservoir is relocated to the right side of the vehicle, which obstructs the path for water hoses.

In case of Audi RS3, you have some room in the engine bay, because the 12V battery is relocated to the trunk.

In case of Audi S3, you can use an aftermarket cold-air intake system for your engine, and use some of the space from the OEM air box to fit the Webasto unit. Other option is to remove the upper part of the washer fluid reservoir (it splits into two parts) and install the Webasto unit there.

When it comes to fitting Webasto unit into Audi S3, I had to remove the units exhaust, units intake, circulation pump, and both mounting brackets. Webasto unit alone has a compact shape and will be easier to find a safe place for it. It will also require to use an universal exhaust once the unit is mounted.

[[File:Audi-S3-8V-extra-radiator.png|thumb|alt=Audi S3 (8V) 2.0TFSI extra radiator on the right side|Audi S3 (8V) 2.0TFSI extra radiator on the right side]]

There are two versions of the Webasto Thermo Top Evo heater unit:
* Diesel (Thermo Top Evo D)
* Petrol (Thermo Top Evo B)

=== Telestart Module ===
* <code>4H0-963-271-E</code> - Audi Telestart module by Eberspächer.

=== Antenna ===
There's a fakra connector on the Telestart module. If Audi A3 is factory fitted with Webasto, module is connected with the roof antenna module. For retrofit there's an additional antenna that you can stick to the cars body.

I will also try to use a generic antenna from AliExpress, just to see if I can pair the remote with it. If there's a change of accessing bottom the OEM roof antenna, I would love to wire the module to it. I believe the roof antenna will provide better signal and higher remote range.

=== Remote ===
There's couple of remotes that you can use. Of course Audi has the coolest one, with the display. But I believe other remotes (VW, Skoda...) should also work, since the heater module is the same for those cars.
* <code>4N0-963-511</code> - Audi, two buttons
* <code>4H0-963-511-A/B</code> - Audi, 4 buttons, red backlight ([[Eberspächer EasyStart R+]])
* <code>4H0-963-511-C/D</code> - Audi, 4 buttons, white backlight ([[Eberspächer EasyStart R+]]) by Eberspächer
* <code>3G0-963-511-D</code> - VW, two buttons
* <code>7N0-963-511-B</code> - VW, two buttons (T91R)
* <code>8K0-963-511 / 7E0-963-511-B</code> - Audi, two buttons

=== Wiring kit ===
I've got one of those, new:
* <code>8V0-054-931</code> - wiring installation kit for Audi A3 8V. ([[8V0-054-931]])
Paid ~€50 for it. And it contains a lot of little things that I believe will be necessary during the installation.

=== Fuel lines and pump ===
=== Coolant pipes ===

Webasto aux heater system contains couple elements:
* Webasto heater unit with water circulation pump, exhaust, and intake
* fuel dosing pump with fuel lines
* water hoses
* wiring harness
* remote start receiver with antenna
* remote control

Webasto unit communicates with related modules like infotainment unit (Audi MMI, VW Discover, Seat Navi...) and HVAC (Climatronic). It will also check ambient temperature, car battery charge, and car fuel level.

[[File:Audi-a3-8v-webasto-retrofit-kit.png|thumb|alt=Audi A3 8V webasto retrofit OEM kit|Audi A3 8V webasto retrofit OEM kit]]

Retrofit kit for Audi A3 8V is available as a whole set of needed parts and accessories:
* <code>8V0-054-960-E</code> - TDI, front-wheel drive (PR-1X0)
* <code>8V0-054-960-D</code> - TDI, all-wheel drive (PR-1X1)
* <code>8V0-054-965-C</code> - 2.0 TFSI, front-wheel drive (PR-1X0)
* <code>8V0-054-965-D</code> - 2.0 TFSI, all-wheel drive (PR-1X1)
* <code>8V0-054-965-E</code> - 1.0, 1.4, 1.5 TFSI, front-wheel drive (PR-1X0)

I can't see an option for 1.8 TFSI, but I assume that it will be the same as for 2.0 TFSI, since both engines are from [[EA888.3]] family and share a lot of components.

Also there's no option for Audi S3 and Audi RS3. Most likely this it caused by the two additional radiators. The one on the right side is taking the space that normally would be available for the Webasto unit. Also the washer fluid reservoir is relocated to the right side of the vehicle, which obstructs the path for water hoses.

In case of Audi RS3, you have some room under the hood, because the battery is relocated to the trunk.
