What this usually means
75% likely the engine mounts (rubber + hydraulic). Real fix $400-700 for the pair. Agent sometimes pushes ECU/transmission diagnosis. Mounts wear at 80-100k km on M274.
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.
