Peugeot 807 Error Messages and Control Unit Issues

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!
