What are the situations of abnormal noises in Audi?
1 Answers
Audi abnormal noises are as follows: 1. Abnormal noise when parking: Noise comes from the bottom of the car. The main reason is the thermal expansion and contraction phenomenon of the three-way catalytic converter at the bottom of the car, which is a normal phenomenon. 2. Abnormal noise when passing speed bumps: The main reason is the looseness of the top rubber or steering rod. After the vehicle rises on the speed bump, the steering rod and bearing will produce regular abnormal noise for a period of time, which is the sound of the ball. 3. Front wheel abnormal noise: The sound from the front wheels when turning, similar to a bouncing sound, indicates a problem with the ball wheel. 4. Engine abnormal noise: After the car is turned off, a hissing sound similar to a hiss will come from the engine of the car. This is usually very regular, and the main reason is the pressure relief of the oil pump.
