M Klasse hybrid electrical gremlin

I had similar issues with my M Klasse Not the hybrid version but the symptoms sound familiar The navigation cutting out and some random electrical quirks Did they check the battery condition Sometimes a weak battery can cause control module glitches

Thanks that's helpful They did mention the battery during the onboard diagnostics check but didn't seem too concerned Was your problem definitely a software issue or something else

It's tough to say definitively I think the weak battery was contributing but ultimately the control unit needed a reflash The shop I went to mentioned something about corrupted data I would say let them do the software fix it is a common problem But it might also be worth checking the battery terminals are clean and tight before that just to rule it out

Appreciate the insight I went ahead with the software fix and it seems to have resolved the issue The navigation is back and the error messages are gone Thanks for the advice
