What this usually means
85% intake valve carbon buildup — known direct-injection TSI issue at 60-80k km. Real fix: walnut blast $400-600. Agent sometimes pushes full intake replacement.
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.
This is not a final diagnosis. It is a money-saving checklist before you go workshop.
