Default Driver Door Electronics

Hi Everyone...please assist. My A6 C7 was involved in a minor accident which required the drivers door and fender to be replaced.

The problem I have is that some functions are inoperable: the drivers wing mirror does not operate from the joystick, but the passenger side works fine from the same joystick.

The central locking works for three doors but not the drivers door.
The 4 window switches work perfectly but the illumination does not come on.

I have followed the coupling in the door post and made sure that all plugs are properly connected inside the car. Done the same for the section going into the door. I swapped out the control module with that on the passenger door. I get the same issues, but the drivers control module on the passenger door works. I have done the same with the central locking actuators with the same results.

Does anyone have any suggestions or a simple wiring diagram which shows which the wiring to the control module and from there to there to the individual components.

Convinced that it is electrical, a wire that schaffed or broken, but cant find it

Sounds like some re-coding might be in order.... A quick VCDS scan might yield some useful information regarding the problems. Good Luck!

hi thanks for the reply.

I launch x431 not vcds. Here's the scan results in the pdf. I've managed to resolve all other issues except the door.

I checked the long coding for all 4 doors and they all show the same long code
