Hi all
I have audi a6 c7 avant 2012
I was fitting a towbar last month with a dedicated wiring loom when i installed everything the car failed to start ( no ignition) only worked radio, headlights, door lock’s operating from inside the car.
I checked all fuses they were fine
Then it was towed to a garage they said body control module failed
They changed for second hand one it was still no ignition after all
Then towed to other specialist they said need’s new module
It was changed and the car up and running again
Only issue the both side of the rear door not operating it’s locked i doesn’t do anything for a window or for door child lock etc
The guy online reprogrammed and coded the bcm he said coding is fine
Is any suggestion what causing the fault i am still thinking something with coding issue but they say door control module
Old module 4h0 907 064 CN
New module 4h0 907 064 GB (ordered from Audi)
