Thanks for the reply Where did you find the software version info Did you sort it yourself, or did you take it in

I am no expert. I looked in the car's settings but took it to a workshop. They ran tests, recalibrated something, and refreshed the software. Problem solved They said the programming was corrupted, so it sounds like the same issue. Let a pro look at it. It might need a proper software refresh and diagnostics check.

Okay, I appreciate the advice A workshop visit seems unavoidable. I will advise if the software refresh sorts it.

That sounds familiar I have a B Klasse too and had a similar experience last year. The navigation would freeze, and I'd get random warning lights. Have you checked the control unit software version? A software refresh can sometimes fix these glitches. It could be a software bug.
