My audi concert system has recently developed a problem in that it won't work..... In the run-up to this failure, it often turned itself on when the car was remotely unlocked.

The LED display will light red - albeit rather dim - but there is no response from any of the buttons and obviously no sound or display.

I have searched the forum threads but have found no info and i apologise if there are threads here that i have overlooked, but i would appreciate any replys you may have.

I fear that it will may cost an arm and a leg to fix and suggested to the wife that we just put a portable radio in the car, but this suggestion was dismissed with fierce derision

BTW - the car is an Audi A4 avant 1.9 TDI 2001.

Cheers.
