hello, I’m in desperate need of some help. My a6 (57 plate) went in to have the rear break pads changed and when I got the car back, the whole control centre was broken. It comes up saying that there is a missing component, contact Audi and then shuts off. Obviously said garage said they didn’t break it and have tried to absolve themselves of all blame but I know they did it - I just don’t know what they did. I know that they broke the motor and had to replace it so my guess would be it’s off the back of that somehow. I got an auto electrician to run a diagnostic on it but he said it would take really long to figure out exactly where the fault was because it was coming up with so many as something in the circuit has tripped. He did however mention that he looped the amp out of the circuit and the control centre came back on again and was usable - just no media functions. I don’t see how this can be though as it was all working fine before it went in? I appreciate this is an odd one but I’ll be so grateful for any light anyone may be able to shed on the issue. Thanks!
