I have a c6 rs6 avant. I've had a new amp fitted as the old one was faulty, after it was fitted there was no sound due to component protection. I took it into audi and they removed the protection but still have no sound coming from the speakers. I've been told it could be the phone module which is under the passenger seat however the Bluetooth connects to the phone and my phone book etc comes up it will make and recieve calls just no sound.
Same with everything else it all works on the screen the reversing camera comes up stereo all works just speakers seem to be inactive.
Is is there anything I can try before having to send my car in somewhere?
