What this usually means
Scirocco 1.4 TSI twincharger faults can be coil/plugs, injector, carbon buildup, supercharger clutch or compression-related. Demand compression data and misfire counters before accepting major engine work.
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
- • Use/confirm: Compression tester
This is not a final diagnosis. It is a money-saving checklist before you go workshop.
