Seat Arosa Audio System Failure

Whoa, that sounds eerily familiar. I had a similar issue with my Arosa’s audio system a while back. The whole thing just died on me, no sound whatsoever. Have you checked the fuses? That was my first thought, but it wasn't that. Also, have you noticed any weird smells, like burning plastic? That could point to some faulty wiring back there. I'd check the volume control too, to see if it's not stuck or dirty. Might be worth a shot before you start tearing everything apart. I'm curious, did you encounter any speaker crackle before it went completely silent?

Burning plastic smell? No, thankfully nothing like that. I did check the fuses, all seem to be fine. The volume control seems okay too, it moves freely, but does nothing. When you say similar, do you mean completely dead, as in zero sound from any of the speakers? And did your error memory also point to the display being defective?

Yep, completely dead. No sound whatsoever. That's exactly why I suggested checking for speaker crackle. It started with the crackle, and then silence. And yes, the error memory also indicated a problem with the display unit. Honestly, based on my experience, and the fact that you're getting a similar error code, I'd say it's highly likely that the display is the culprit. I ended up taking mine to a workshop. They confirmed the diagnosis and replaced the unit. It wasn't cheap, but at least it fixed the problem. I would suggest you do the same, as it is not easy to fix.

Alright, thanks for the heads-up. I took it to a workshop as you suggested. Turns out the display unit was indeed fried, just like the error memory suggested. The whole thing cost me 725€ including parts and labor. At least the speakers are working again and the crackle is gone. Now I can finally crank up the volume without wanting to throw the whole audio system out the window. I appreciate your help!
