Noises in a Volkswagen car may be caused by body noise, interior noise, brake noise, and other reasons, as detailed below: Body Noise: Body noise is the most common issue, usually due to insufficient body rigidity. Long-term aggressive driving or frequent travel on bumpy roads can cause slight deformation of the body frame. The most direct effect is abnormal impact or friction between the doors and the body, or abnormal friction at welding or screw points, which may also cause noise. Additionally, some cars produce more noise, which is partly related to the vehicle's design. Interior Noise: Noises inside the car can originate from multiple areas, such as improperly installed trim panels, a loose glove compartment on the passenger side, or seatbelt buckle collisions. Brake Noise: If a squeaking sound occurs when braking, it is often due to excessive wear of the brake pads, creating unwanted gaps. Improper material use or deformation of the brake discs, as well as issues with the hardness, porosity, friction characteristics, or compression characteristics of the brake pads, can also lead to noise. Tire Noise: Tire-related noises are generally referred to as tire noise, and the sound intensity varies depending on factors such as driving speed, tire type, tire pressure, and road conditions. A low, thudding sound often indicates tire tread deformation, bulging, severe wear, or insufficient pressure. A tapping sound, on the other hand, may be caused by small stones stuck in the tread or a puncture from a nail.
