How to solve the air system fault code of BMW x5 engine 2d06?

There is something wrong with the air sensor or the pipe leaks. It can be solved by changing the valve cover.

Engine maintenance skills:

Clean the air filter. The air filter is directly related to the air intake of the engine when the car is running. If the air filter is blocked or there is too much dust, the air inlet of the engine will be blocked, and a large amount of dust will enter the cylinder, which will accelerate the carbon deposition speed of the cylinder, which will hinder the ignition of the engine and cause insufficient power, and the fuel consumption of the vehicle will naturally increase.

If you drive on a normal city road, you should check the air filter when the car travels 5000 kilometers. If there is too much dust on the filter element, consider using compressed air to blow out the dust inside the filter element. But the pressure of compressed air should not be too high to avoid damaging the filter paper.

2. Remove the throttle oil sludge. There are many reasons for sludge at the throttle, some of which are carbon deposits formed by exhaust gas from fuel combustion at the throttle; Then, impurities that are not filtered by the air cleaner will remain on the throttle. Too much sludge will cause air resistance and increase fuel consumption.

Extended data

Engine classification:

1, horizontally opposed engine. The included angle formed by V-shaped layout is usually 60, while the included angle of cylinders in horizontally opposed engine is180. However, the manufacturing cost and technical difficulty of horizontally opposed engine are quite high, so at present, only two manufacturers, Porsche and Subaru, are using it in the world.

2. Rotary engine. Compared with the common L-type and V-type cylinder layout. The rotary engine, also known as Miller cycle engine, was invented by the German Figas Wankel. The rotary engine cancels the useless linear motion, so the rotary engine with the same power is smaller, lighter, and has lower vibration and noise, which has great advantages.

3.VR engine. The VR engine is the exclusive product of Volkswagen. 199 1 year, Volkswagen developed a V62.8L engine with an included angle of 15, which was called VR6 and installed on the third generation golf. This kind of engine is compact in structure, close to the in-line engine in width and not much longer than the in-line 4-cylinder engine in length.
