What is the reason why BMW x5 has abnormal sound when stepping on the accelerator?

Abnormal sound of BMW x5 stepping on the accelerator is caused by abnormal sound of gasoline pump motor, abnormal sound of accelerator, poor lubrication of accelerator pedal bearing and damage of clutch release bearing. Details are as follows:

Abnormal noise of gasoline pump motor:

When the gasoline pump motor is worn or has impurities, stepping on the accelerator will make an abnormal sound. This problem requires replacing the gasoline pump.

Abnormal throttle sound:

The gear of the motor is worn and insufficiently meshed, resulting in abnormal sound. Excessive carbon deposition in the throttle can also lead to abnormal throttle sound. The throttle can be cleaned. If the motor is damaged, remove the throttle and replace the servo motor.

Poor lubrication of accelerator pedal bearing:

Poor lubrication of the accelerator pedal bearing leads to abnormal noise, and the bearing can be lubricated by itself.

Clutch release bearing damaged:

The clutch release bearing is damaged, resulting in incomplete separation of clutch plates and abnormal noise. Remove the clutch and replace the release bearing.
