What this usually means
V-Class sliding-door faults are often latch, roller alignment, sensor or wiring before full motor replacement. Ask for live data and mechanical alignment check first.
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: Star Diagnostic XENTRY
This is not a final diagnosis. It is a money-saving checklist before you go workshop.
