What causes the abnormal noise in Audi Q5?

[LaDavid]

Audi Q5 may produce abnormal noise due to the following reasons: Exhaust pipe deformation: In most front-engine models, the exhaust pipe runs from the bottom of the vehicle to the rear. When driving on rough roads or if the undercarriage is impacted, it can easily cause the exhaust pipe to dent or deform. A deformed exhaust pipe increases exhaust resistance, resulting in a buzzing sound and vibration sensation. Loose parts: Some components of the vehicle may become loose, such as the fender or engine compartment cover panels. It could also be due to the thin sheet metal parts of the vehicle, which may vibrate and resonate during high-speed driving. Engine abnormality: Abnormal engine noise indicates a change in the technical state of a certain engine mechanism. This is mainly caused by excessive wear of some parts or improper assembly and adjustment. Some abnormal noises may even signal potential catastrophic engine damage. Therefore, when abnormal engine noise occurs, it should be repaired promptly to prevent further damage.
