What are the reasons for abnormal noises when driving an Audi Q5?
2 Answers
Audi Q5 may produce abnormal noises while driving due to the following reasons: 1. Tensioner pulley wear: The tensioner pulley's function is to tighten the engine belt, preventing the generator and power steering pump from slipping. Due to prolonged pressure and high-speed rotation, the bearings inside the tensioner pulley are prone to wear, resulting in noise and resonance. When it is confirmed that the buzzing sound and resonance are caused by the tensioner pulley, the engine mounts should also be checked, as their role is to reduce vibrations and noise generated by the engine. 2. Exhaust pipe deformation: Generally, in front-engine models, the exhaust pipe extends from the bottom of the car to the rear. Driving on rough roads or impacts to the chassis can easily cause the exhaust pipe to dent and deform. A deformed exhaust pipe increases exhaust resistance, leading to a buzzing sound and resonance. 3. Wheel hub bearing wear: The wheel hub bearings are installed in the suspension's "knuckle" and constantly bear the vehicle's weight and impacts during daily driving. The bearing balls inside are prone to wear, and the most typical symptom of bearing wear is a buzzing sound and resonance in the car.
I've been driving an Audi Q5 for several years, and the annoying noises while driving are quite bothersome. It's often tire-related issues, like low tire pressure or stones stuck in the tread, especially making a thumping sound on uneven roads. The braking system could also be the culprit—worn brake pads or loose calipers can produce a sharp squealing noise. The suspension system shouldn’t be overlooked either; a faulty shock absorber or aged bushings can cause a rattling sound. Whenever I hear noises while driving, I first check these areas and then take a quick look at the tire condition. If the noise is frequent, it’s best to get it inspected at the dealership to avoid potential accidents—safety comes first. Regular maintenance of tires and brakes can prevent many issues, making highway drives much quieter.
