Checked it how? I mean, I saw the error message. Is there a way to check the battery myself? What did you do to solve it?

No, I didn't check it myself. When I had the same symptoms, error codes and everything, the dealer told me the battery was heavily discharged. I took it to the shop and they sorted it out. I would recommend doing the same.

Ok, thanks. It turns out it was a heavily discharged battery, just like you said. Cost me 290€ to get it sorted. I appreciate the help.

I had a similar issue with my E Klasse hybrid. I'm not sure about the voltage sensor, but it sounds like battery drain to me. Have you checked the battery?
