Power boot retrofit
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!

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.
