Talisman MOST Bus Fault

I'm at my wit's end! My 2021 Renault Talisman diesel is giving me grief. The audio system is dead, no sound whatsoever, and the navigation is out too. The diagnostics points to a MOST bus fault. Has anyone encountered this?

I had similar issues with my Talisman. MOST bus faults are nasty. Does the error memory also show a fault?

Yes, the error memory is showing a fault related to the MOST bus. What was the cause in your case?

Most likely, one of the control units on the bus is faulty. I’d advise a workshop visit. Replacing the faulty control unit fixed my issue.

Thank you! I'll take it to the workshop. I was hoping it was something simple that I could fix myself, but it looks like it's more complicated than that. The repair will probably cost me around 1000€, but at least the car will finally work as it should
