Master Electric Audio System Failure

I had a similar problem with my Master. No sound at all, right? Did you check the fuses? Also, does the display turn on, or is it completely dead?

Yeah, completely dead. Display doesn't turn on. I checked the fuses, they seem fine. What was the solution for your car?

Sounds exactly like what I experienced. In my case, the display unit itself was defective and needed replacement. I'd suggest taking it to a workshop; they'll be able to diagnose it properly. My repair cost around 725€.

Thanks for the advice! I took it to a shop, and you were right, the display was defective. They replaced it. Now it's working again!
