Is the BMW accelerator under warranty?

The BMW accelerator is under warranty. There is no strict limit on how often the throttle is guaranteed, which is related to the habit of using the car and the environment. If it is dirty, it should be washed. Phenomenologically, cleaning should be considered when the idle speed is unstable. Under normal circumstances, the 4S shop will advise the owner to clean it once every 20,000 kilometers. Of course, the situation is different for different models. It is also common for some cars to have dirty gas throttles, and it is serious to clean seven or eight thousand kilometers.

Throttle valve principle

There are two kinds of throttles: traditional cable throttle and electronic throttle. The traditional engine throttle control mechanism works by pulling a cable (soft steel wire) or a pull rod. One end of the cable is connected with the accelerator pedal, and the other end is connected with the accelerator linkage plate. The electronic throttle mainly controls the opening of the throttle according to the energy required by the engine through the throttle position sensor, so as to adjust the air intake.
