What this usually means
X3 knocks are usually control arms, sway links, top mounts or worn bushings before full shock replacement. Ask for lifted inspection proof of play/leak.
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.
