I'm wondering if it's possible to retrofit power boot into Audi A3 8V sedan? Just like in other VAG sedans - Audi A8 or A6 or A4 or VW Passat? And since Passat is also made on MQB platform, I'm going to assume that it will work in A3 with a help of Audi Q2 or Q3 parts. Hope that I'm right...
Retrofitting in limousine/sedan body it should be simpler than in hatchback or sportback, since there are no struts. Will it be enough to replace the boot balancing spring with servo motor, replace the trunk lock with soft-close one, add the module, add wiring, closing button, perform coding, basic settings...?
Ok. Actually it's a lot. But it should be possible!
Schematics

Parts
Servo
There's couple version of the Stabilus Powerise servo motor that operates boot in VAG sedans:[1]
- 3G5-827-851 from VW Passat B8
- 4G5-827-851-B from Audi A6 C7
- 4K5-827-851-C from Audi A6 C8
- 4N0-827-851-A from Audi A8 D5
The cheapest would be the best. I don't need much torque in Audi A3 8V - my trunk door should be lighter than the one in Passat.
But it looks like there's an even cheaper option:
- 4G8-827-852-B from Audi A7 C7
Not sure how exactly this mechanism works but it's the cheapest one there. It might be worth getting one just to try if it can operate in Audi A3 8V.
Trunk module
- 5Q0-959-107-F /K from VW Passat B8
- xxx-xxx-xxx from Audi Q2 or Q3 ?
Trunk lock
- 81A-827-506 from Audi Q2 and Q3
Wiring
- 3G5-971-147-AP from VW Passat B8
- xxx-xxx-xxx from Audi Q2 and Q3?
Buttons
I want to have while backlight in both the trunk closing button (trunk door) and trunk opening button (drivers door).
- 8V0-959-831-B - trunk opening button from Audi A3 8V facelift
- 8V5-959-829 - mounting frame for trunk opening button in
- 4G0-959-831-C - white backlight trunk closing button
Kick-open sensor
This is optional.
- 3G0-962-243[2]
Warning buzzer
- xxx-xxx-xxx ???
Installation

Coding & adaptation
Adding trunk door control module to the gateway list of installed modules.
Module 0x19 → Adaptation → Installation list, specified installations → Deck Lid Control Unit → coded
Adjusting coding of the trunk door module.
Module 0x6D → ???
Adding Virtual Pedal - Kick open.[3]
Adding information to the BCM that trunk door release is controlled directly.
Module 0x09 → Security Access → 31347 Module 0x09 → Adaptation → Access Control → Direkter Auswurf des Heckdeckels → active
Enabling trunk opening button in drivers door.
Module 0x42 → Long Coding → Byte 02 → Bit 3 → enabled
Basic settings
Procedure for basic settings of the power trunk door:[4]
- Make sure that the trunk door is closed.
Module 0x6D → Basic Settings → Rear lid basic settings- Open the trunk door from the remote button or from the button in drivers door.
