Reasons for Audi a6 burning engine oil

The EA888 engine of Audi A6L is easy to burn oil, which is a designer's design defect. This problem exists in German cars equipped with this engine, and you are not the only one.

First of all, you have to confirm the reason for burning oil. There are two main reasons for burning engine oil. First, there are problems with accessories, waste gas valve, valve oil seal, cylinder pulling and insufficient cylinder pressure. Second, the oil circuit is not cleaned for a long time, the antifreeze is not replaced in time, the service life of the oil is too long, and the piston ring is stuck. The common situation is that the piston ring is stuck.

From the market experience, German car parts are not easy to go wrong. Most EA888 engines burn oil because the piston ring is stuck. The stuck oil starts from the oil circuit, and the bearing temperature of the oil is 1 10 degrees. However, the high temperature caused by the long-term uncleanness of the oil circuit makes the oil stay above 120 degrees for a long time, so that the oil will be exhausted in advance, resulting in small holes in the oil ring. The oil in it will be crusted by baking for a long time. One cylinder is stuck at 5000 kilometers per liter of oil. At this time, the working conditions of other cylinders will start to be bad, and soon all four cylinders will be stuck, becoming per liter of oil 1000 km or even hundreds of kilometers. Therefore, to solve the problem, we must start with the root oil circuit, which is the way to get rid of the root.

At present, there are two solutions in the market, one is overhaul, and the other is PNF maintenance agent. If it is overhauled, the cost will be high, the vehicle will depreciate quickly, and the later running-in will be very troublesome. It's not that there is no way out, so this step is not recommended. I've seen riders repair it with PNF restorers before. You can refer to it
