Peugeot 407 Sporadic Errors

I have a 2009 Peugeot 407 with a gasoline engine and lately, it's been acting up. I'm getting sporadic errors - sometimes a warning signal, other times it affects audio/navigation. Sometimes the system just quits. Any thoughts? My scan tool shows an error, so service is required, right?

A 2009 Peugeot 407 is experiencing sporadic errors, including warning signals and system shutdowns affecting audio and navigation. The issue may be related to the car's control module or BUS system, possibly due to a faulty cable connection. It is advised to have the vehicle checked at a workshop to accurately diagnose and resolve the problem.

Hey, that sounds familiar. I have a 407 as well. Are the errors related to the car's control module, maybe a BUS system problem? I had similar issues with temporary shutdowns. Is it the same control unit failure?

Control module... BUS system? Hmmm. How did you figure that out? Did you see the same error lamp come on, or systems crashing completely? Because that's exactly what's happening to me. What else could it be?

Well, based on what you're describing, it definitely sounds like the same thing. I'd get it checked at a workshop, if I were you. They can pinpoint the cause of the issue. For me, it was definitely the cable connection of the control unit

Will do. I'll book it in. I'll let you know what happens in the workshop. The estimated repair cost for cable replacement on the control unit is 155€
