How often does Audi a4 throttle need to be cleaned?

Under normal use of Audi a4, the throttle valve is cleaned every 20,000 kilometers or so. There are two ways to clean the throttle: disassembly cleaning and disassembly-free cleaning. The disassembly and cleaning are relatively clean and can be cleaned in all directions. After cleaning, the on-board computer is required to cooperate with the throttle.

It is necessary to clean the throttle, because the flexibility of the vehicle speed is closely related to the cleanliness of the throttle, and cleaning the throttle can even achieve the purpose of improving efficiency and saving fuel. If you drive for a long time, the throttle will accumulate some dirt. When there is too much dirt, it will often lead to insufficient air intake of the engine, which will lead to unstable idle speed of the engine. When driving, it suddenly feels like turning off the throttle and reducing the power. In severe cases, it will even lead to problems such as difficult start-up and increased fuel consumption. When the above phenomenon occurs, the throttle valve needs to be cleaned.

The function of throttle valve is that when the piston does work, air will enter the engine and mix with gasoline to form combustible mixture, and combustion will provide kinetic energy. One side is the air filter, and the other side is the engine body, which controls the air intake of the engine. The amount of work done by the engine depends on the depth of the throttle. The deeper you step, the greater the throttle opening, the more air intake of the engine, the more oil and gas combustion and the stronger the power.
