What this usually means
Frameless-door window issues are often regulator, guide, pinch protection or basic adaptation. Ask the workshop to test the regulator and recalibrate before replacing control modules.
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.
- • Use/confirm: ODIS
- • Use/confirm: VCDS
This is not a final diagnosis. It is a money-saving checklist before you go workshop.
