A 2021 Citroen Jumper electric is experiencing sporadic electrical issues, including driving mode errors, flashing error lamps, and control unit shutdowns. Diagnostics suggest BUS system issues, possibly due to a loose cable. A similar case was resolved by fixing the BUS system cable, costing 155€. The recommendation is to have a professional service check the BUS system connections to resolve the problem.

Mostly generic codes, pointing to communication errors rather than specific module failures. Did you ever find the culprit? And if so, what was the carnage to your wallet?

Yep, BUS system cable was the rascal. Shop diagnosed it quick and got it sorted for 155€. But seriously, those symptoms are a carbon copy of my issues. Save yourself the headache and take it in; chasing ghosts in the wiring loom isn't fun.

Cheers for the insight! Sounds like I'm heading to the shop then. Just got the official diagnosis - it's exactly what you said, BUS cable. At least now I know they're not ripping me off!

Sounds painfully familiar. I had similar chaos with my Jumper, like a poltergeist was messing with the electrics. Check the BUS system connections, sounds like you're on the right track. Is it throwing codes that implicate specific modules or is it more generic?
