C2 electrical issues

Hey, I'm having strange electrical issues with my 2005 Citroen C2 diesel. It has 127176 km on the clock. Sporadic errors in driving mode, sometimes error lamps light up. Various systems fail intermittently, mostly in the audio/navigation area. Sometimes control units temporarily shut down or become unresponsive. I ran an OBD-II scan and there's an error stored. Any ideas?

Sounds familiar. I've got a C2 as well, and I had similar problems. Did you check the BUS system?

Thanks for the quick reply! By BUS system, do you mean the CAN bus? If so, what specifically should I be looking for?

Yeah, the CAN bus. I didn't dig too deep myself, but the workshop mentioned something about a defective cable connection to the control unit causing it. Best get it checked professionally.

Okay, thanks for the advice! I took it to a workshop to have the cable connection of the control unit checked. Turns out it was indeed a defective cable connection to the BUS system of the control unit. Cost me 155€, but everything works fine now. Thanks again!
