S80 Audio System Failure

I had a similar issue with my old BMW. The entire audio stopped – no radio, no CD, nothing. It was a fault in the central control unit. Have you checked the fuses and the connections to the head unit?

Thanks, I checked the fuses, and they seem fine. Can you tell me more about the central control unit fault you had?

The BMW dealer confirmed the diagnosis. They said the control unit wasn't communicating properly on the CAN bus, which shut down the audio. Best bet is a workshop visit.

Thanks. I'll get it to a workshop to diagnose the audio system problem. The invoice came up to 725€ - the display was indeed defective.
