What this usually means
F10 oil smell is commonly valve-cover gasket, oil-filter housing gasket, or oil pan gasket. Ask the workshop to clean and trace the leak source before quoting several gasket jobs together.
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: ISTA
This is not a final diagnosis. It is a money-saving checklist before you go workshop.
