A BUS system issue, huh? Where should I start checking? I've got a basic scan tool but nothing fancy. Could a bad cable really cause all this chaos?

Yes, a defective cable connection to the BUS system is a possible culprit. Based on my experience, I'd suggest having it professionally diagnosed, even if you have a scan tool. In my case there were shorts in the cable harnesses that were causing similar symptoms, so I went to the workshop and got it sorted out.

Thanks a lot for the insights! I'll take it to a workshop. I suspected something along those lines. Turns out it was exactly what you suggested, a defective cable connection, and the repair cost was 155€. Really appreciate the help!

I had a similar issue with my Peugeot Traveller. Does it seem like a BUS system issue? I'd suggest getting engine diagnostics run; sounds like a potential cable connection problem to the control unit.
