What Are the Causes and Solutions for Audi Cars Burning Engine Oil?
1 Answers
Audi cars may experience engine oil burning due to several possible reasons: piston ring sticking, sealing issues in the combustion chamber; long-term lack of maintenance leading to excessive sludge buildup and oil passage blockage; wear; corrosion and aging of valves; and ventilation and exhaust system malfunctions. Below are the solutions for engine oil burning: 1. Replace the valve stem seals: A common solution for BMW and Audi cars burning oil is to replace the valve stem seals, which does not require a major engine overhaul. Replacing the valve stem seals has proven to be very effective in addressing engine oil burning. During repairs, it has been observed that in German cars like BMW and Audi, oil leaks leading to oil burning often originate from the valve stem seals due to poor sealing, which allows oil to seep into the combustion chamber and mix with fuel for combustion. A blue smoke emission can be seen when starting the car. Identifying this fault and replacing the valve stem seals can resolve the issue. 2. Clean carbon deposits: Due to the difference in fuel quality standards between domestic and international markets, engines are prone to forming significant carbon deposits in the combustion chamber during operation. Carbon deposits are a major cause of various engine problems, including oil burning. During routine car maintenance, specialized cleaning equipment can be used to perform non-dismantling cleaning on areas prone to carbon buildup, such as the intake manifold and oil passages.
