15, 1.5T Fox, when you step on the accelerator, you will have a gasp.

15 1.5T The wheezing sound made by Fox when stepping on the accelerator is: abnormal noise of the gasoline pump motor. Abnormal throttle sound.

Abnormal sound of gasoline pump motor. When there is wear or impurity inside the gasoline pump motor, it will make an abnormal sound when we step on the accelerator. This problem requires replacing the gasoline pump.

Abnormal throttle sound. At present, the throttles are all electronic throttles, and it is naturally the motor that controls the opening and closing of the valves. When the motor gear is worn, the bite is not sufficient, resulting in abnormal sound. When there is too much carbon deposition in the throttle, it will also cause abnormal noise in the throttle. The throttle can be cleaned. If the motor is damaged, remove the throttle and replace the servo motor.
