Having problems with your 2007 Audi A6 Avant Wagon ?
I have a 2007 A6 avant with MMI Basic inc sat nav and bluetooth. It all worked perfectly when I bought the car a few months ago. Then it started switching itself off after an hour or so of driving. During the process the speakers make a cracking sound and the MMi reboots around 10-15 times before staying on for good for the whole journey but with no sound. Everything functions fine with the MMI but there is no music, sat nav voice or BT. I took it to main Audi dealer and they disconnected the BT
I bet that rear screen washer lines are broken and fluid damaged electronic under trunk trim.
