What this usually means
85% software-fixable via XENTRY firmware update ($150-250). Agent often quotes full COMAND replacement ($2,500+). Software update first, hardware replacement only after that fails.
What to ask the workshop before approving repair
- • Show the diagnostic fault codes.
- • Show photo/video proof of the failed part.
- • Give an itemised quote for parts and labour.
- • Explain why cheaper common fixes were ruled out.
This is not a final diagnosis. It is a money-saving checklist before you go workshop.
