What this usually means
EPC light can come from throttle body, boost leak, coil pack, sensor or turbo-control faults. A scan is essential because guessing parts gets expensive quickly.
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.
