Audi A6 Avant amplifier fault

I own a 2011 Audi A6 Avant. A few days ago the sound system stopped working. This happened after my car had some work done at my local dealer for a faulty central locking unit. The fault results in no sound at all and inability to use hands-free telephone. Is it a coincidence that this has stopped working at the same time the dealer worked on the car?

Get it to an independent car audio specialist, and if he tells you the dealer damaged the amp then force the dealer to pay for the repair using the small claims track of the county court if necessary.
