Webasto retrofit

Parts

Retrofit kit for Audi A3 8V is available as a whole set of needed parts and accessories:

• 8V0-054-960-E - TDI, front-wheel drive (PR-1X0)
• 8V0-054-960-D - TDI, all-wheel drive (PR-1X1)
• 8V0-054-965-C - 2.0 TFSI, front-wheel drive (PR-1X0)
• 8V0-054-965-D - 2.0 TFSI, all-wheel drive (PR-1X1)
• 8V0-054-965-E - 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 family and share a lot of components.

Webasto Heater

There are two major versions of the heater unit: diesel and petrol. TODO

Telestart Module

• 4H0-963-271-E - Audi 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.

• 4N0-963-511 - Audi, two buttons
• 4H0 963 511-A/B - Audi, 4 buttons, red backlight (T100?)
• 4H0 963 511-C/D - Audi, 4 buttons, white backlight (T100?)
• 3G0-963-511-D - VW, two buttons
• 7N0-963-511-B - VW, two buttons (T91R)
• 8K0-963-511 / 7E0-963-511-B - Audi, two buttons

Wiring kit

I've got one of those, new:

• 8V0-054-931 - wiring installation kit for Audi A3 8V.

Paid ~€50 for it. And it contains a lot of little things that I believe will be necessary during the installation.
