What Causes the Humming Sound in Audi A5?
1 Answers
Audi A5 may produce a humming sound due to damaged wheel bearings or loose screws. Below are the possible causes and solutions for the humming sound in Audi A5: Damaged Wheel Bearings: First, inspect the wheel bearings. To check, lift the car on a stand, put it in neutral, and release the handbrake. Then, quickly rotate each of the four tires by hand while placing your ear close to the tire to listen for any humming sound. If a humming sound is detected, the wheel bearing is damaged and needs to be replaced. Loose Screws: It could also be due to loose screws. It is recommended to check if the engine oil level is normal. The A5 is a high-quality car as it is an import, and most chassis noises are engine-related, likely due to low oil levels. Adding engine oil may resolve the issue.
