Volvo V50 Electrical Fault
Summary of the thread
A 2009 Volvo V50 diesel is experiencing sporadic error messages, random warning lights, and issues with the audio and navigation systems. The problem may be due to a defective cable connection to the control unit, possibly within the BUS system. The suggested solution is to have a workshop perform diagnostics to identify and repair the faulty connection, which resolved the issue in this case.

A defective cable connection, huh? Interesting. How did you eventually track it down? Was it something you could see visually, or did you have to use a multimeter or something to test for continuity? And which control unit was giving you trouble? I'm not even sure where to start looking on my V50.

It was a real pain to diagnose! I eventually took it to a workshop because I couldn't figure it out myself. They used some fancy diagnostics to pinpoint the exact cable. It wasn't visually obvious; the cable looked fine, but apparently, there was some corrosion or something causing a bad connection. So, no, I wasn't able to fix it myself. They found the problem to be in the BUS system. So I suggest going to the workshop.

Thanks a lot for the insights! I took your advice and brought it to my local garage. They ran some diagnostics and, sure enough, it was a dodgy cable connection to the control unit as you suggested! Cost me 155€ to get it sorted, but at least the gremlins are gone. Appreciate the help!

That sounds frustrating! I had a similar issue with my old Opel Astra. I was chasing a ghost in the machine for weeks. Random failures of different systems, error lights popping up... drove me nuts! Have you checked the BUS system? In my case, it turned out to be a defective cable connection to the control unit. Might be worth a look.
