Audi Q7 burning oil issue requiring explanation on Audi Q7

Some Audi Q7 owners report experiencing oil burning issues, commonly attributed to worn piston rings that fail to seal the combustion chamber properly. Additionally, oil loss may occur due to problems like a faulty sump seal or oil filter, leading to potential leaks. This excessive oil burning can result in harmful deposits within the engine, risking clogging in critical areas such as the catalytic converter and increasing pollutant emissions, which may cause the vehicle to fail emissions tests. While some oil consumption is normal as engines age, needing to add a quart every 1,000 miles or less is considered excessive and signals a need for attention. To address these concerns, many owners find that replacing the piston rings and valve oil seals is the most effective solution to prevent oil from entering the combustion chamber and burning during operation.
