Battery is my suspicion too. Did you experience similar system failures? And did the fault memory also show overvoltage?

Yes, the fault memory showed similar overvoltage entries. Various systems were going haywire. Replacing the car battery sorted it out, although a workshop visit is recommended to confirm.

Car battery was indeed the culprit. Replaced it, cleared the codes, and everything seems stable. Total damage: 290€.

Overvoltage issues can be tricky. I had something similar with my Tarraco. Check the car battery first. A failing battery can cause all sorts of electrical gremlins. Any recent work done on the car electronics?
