How to Solve Severe Oil Burning in Audi Q7?
1 Answers
The reason is the aging or damage of the valve stem seals, or the aging or sticking of the piston rings. The most thorough solution is to overhaul the engine and replace the piston rings and valve stem seals. Adding engine repair additives, choosing qualified fuel or changing the oil grade, and cleaning engine carbon deposits can alleviate the issue but cannot completely cure it.
