What causes the buzzing sound near the right rear wheel after the Magotan is turned off?

This situation is quite normal. It is the sound of the exhaust pipe contracting, and the noise will disappear after a few minutes. Models equipped with electronic parking brakes may also experience this phenomenon, which is the sound of the electronic parking brake motor and is also normal. More relevant information is as follows: 1. Electronic parking brake: The electronic parking brake is a technology that achieves parking braking through electronic control. Its working principle is the same as that of a mechanical handbrake, both of which rely on the friction generated between the brake disc and brake pads to control parking braking. The only difference is that the control method has changed from the previous mechanical handbrake lever to an electronic button. 2. Car exhaust pipe: The thermal expansion and contraction of the car exhaust pipe occur because when the car is running, the combustion of gasoline undergoes complex chemical reactions, and part of the energy is converted into heat energy, which is discharged through the exhaust system. The muffler is basically at the end of this system and serves to reduce the noise of the exhaust. The muffler has to withstand the impact of hot airflow during operation, so it naturally heats up. After the engine is turned off, due to thermal expansion and contraction, a whooshing sound will be emitted for a while. Sometimes the sound may be relatively loud, but this is all a normal phenomenon.
