What this usually means
If the warning appeared after windscreen replacement, bumper repair, or alignment work, calibration is more likely than sensor failure. Ask for calibration proof and fault codes before buying a new camera or radar module.
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: ADAS calibration equipment
- • Use/confirm: EV diagnostic scanner
This is not a final diagnosis. It is a money-saving checklist before you go workshop.
