Peugeot 807 Error Messages and Control Unit Issues

My 2008 diesel 807 is throwing a wobbly. It's showing sporadic error messages, warning lights, and the audio/navigation is cutting out. Control units are going dead for a sec. Error memory has some strange stuff. Any ideas? Anyone seen this before?

A 2008 Peugeot 807 was experiencing sporadic error messages, warning lights, and issues with the audio/navigation system, with control units intermittently failing. The problem was identified as a defective cable connection to the BUS system on one of the control units. The solution involved having a mechanic repair the faulty connection, resolving the issue for a cost of approximately 155€.

Sounds familiar! My 807 used to go bonkers with system failures. Everything would light up like a Christmas tree sometimes, other times nothing at all. Had some message about service required pop up as well. Did you ever have that?

Christmas tree effect, yeah pretty much! You say 'was'? How did you fix it? What was the deal?

Well, 'fixed' is a strong word. More like got someone else to fix it, haha! Seriously though, it was a dodgy connection to the BUS system on one of the control units according to the workshop, so basically the cable connection of the control unit was defective. Cost about 150€. I'd say get it to a proper mechanic to check it out.

Thanks a bunch! Garage confirmed it was the connection thing and sorted it, exactly as you said! 155€ including diagnostics. Sorted!
