Yeah, I did a scan, and it's showing some errors related to the BUS system, whatever that is. Could it be a dodgy connection somewhere? The errors are always intermittent, which makes it even more annoying!

The BUS system thing sounds familiar, that was my problem too! In the end, a mechanic told me the cable connections to the control unit were defective. I'd get it checked out professionally if I were you. It's probably a similar issue.

Thanks for the heads up! I took it to a workshop, and you were spot on – a faulty cable connection to the control unit. Cost me 155€ to sort out. At least it's fixed now!

Sounds frustrating! I had something similar with my old Peugeot, though not exactly the same symptoms. Warning lights flashing for no reason, the infotainment system crashing. Did you hook it up to a scan tool to see if any error codes pop up?
