V90 Audio Failure

A completely dead audio system on a V90... that's unusual. Have you noticed any other anomalies with the display? Sometimes a failing display can take down the whole audio system. It's all interconnected. Also, any recent electrical work done on the car that might coincide with the problem starting?

The display seems fine, with normal visual output and touch responsiveness. Can you elaborate on how a display issue might cause a complete audio system failure? No recent electrical work has been done.

The display isn't just a screen; it's essentially a computer that controls a lot of the car's functions, including the audio. A glitch in its software or a hardware fault that doesn't necessarily affect the visuals could still mess with the audio output. If the system thinks there's a fault in the display's audio processing, it might shut down the whole sound system as a safety measure. Given that it's throwing an error code, and you've checked the basics, I'd strongly recommend getting it professionally diagnosed. Could be cheaper than chasing ghosts.

I brought the car to my local Volvo workshop. As suspected, the display was defective and needed to be replaced. The repair cost was 725€.
