Rifter MOST Bus Audio Failure

That sounds familiar! I had a similar issue with my Rifter a while back. No audio, nav dead... it was a nightmare. Was anything happening before it went out, like did you hit a bump or install something new?

No, nothing out of the ordinary happened. I was just driving along, and the audio cut out. I didn't install anything new recently, and the roads were fine. Did you ever figure out what caused yours?

Yep, after a load of diagnostics it turned out to be a faulty module on the MOST bus. It's a data transmission issue apparently. Unless you're really comfortable with car electronics, I'd suggest taking it to a workshop; they'll be able to pinpoint the exact module that's causing the problem.

Thanks a lot for your advice! It does sound like it's beyond my capabilities. I took it to a workshop, and they confirmed it was a faulty module on the MOST bus. The repair cost me 1000€, but at least everything is working perfectly again.
