Audi C7 MIB2 no sound, no radio stations, tuner error - carmaxlt - 08-08-2022
Hello,
Audi C7 all of a sudden sound disappeared. There is no radio stations, manual FM tuning gives 0mhz. I tried to update firmware and Im getting error "No communication with device: Tuner:0". I have also tried Amp sound test for speakers and im getting beep on some speakers (considering amp is working fine).
Did anybody had similar problems and knows how to fix this?
Thanks in advance.

Bad tuner IC/DSP (SAF7741HV), or something in that area. Needs H/W repair for sure.

Thanks for reply. Could there be no sound because of tuner?

All D/A conversion is done in SAF7741....
