I'm in the process of retro fitting an auto dimming mirror to my 2008 A6 Avant (C6) (auto lights and wipers from factory)
Can someone tell me where on the J519 / CCM that I can pick up the reverse signal please?
I've found lots of conflicting information and this link doesn't mention a reverse signal, only a reverse switch: Audi Portal: ECU Diagnostic . Audi A6 4F (2005- ) . Central Electric I J519
