I have a 2006 a6 tdi avant with mmi fault, turn it on and display says audi mmi etc then goes blank nothing happens and nothing works?????

Took it to audi they said it was controls on centre console, had a electronics guy check the circuit board in there and he said it looked fine!!!!

HELP PLEASE

It can be either the MMI panel or the MMI controller. Only way to tell is with diagnostics, usually the fault is listed in the error codes.

Where is the mmi controller, any idea how much this is ??

What are the fault codes to lookout for??

Thanks
