Audi A4 Makes Abnormal Noise When Turning Over Speed Bumps
2 Answers
Audi A4 makes abnormal noise when turning over speed bumps due to the following reasons: Too small clearance: Friction between plastic components The steering wheel is composed of various plastic parts. If the clearance is too small, abnormal noise will occur when turning, especially for new cars. It usually disappears after a break-in period. Oversized floor mats: Friction between steering column and floor mats Sometimes the installed floor mats are too large and directly contact the steering column, causing friction when the steering column turns. Clock spring issue: Faulty clock spring in steering wheel If the steering wheel has been disassembled before, special attention should be paid as it may be caused by a broken clock spring or improperly connected clock spring plug.
My Audi A4 used to make strange noises when turning over speed bumps too, and I researched it for quite a while. The issue usually lies in the suspension system, such as aging shock absorber springs or loose suspension ball joints. When turning, the body tilts and the bump impact exposes these worn parts. Tire imbalance can also amplify the noise, especially during high-speed turns. Leaving it unrepaired for a long time will accelerate the wear of chassis components and even affect braking performance. I recommend checking the shock absorber top mounts as soon as possible – if they're cracked, they need to be replaced. Regular maintenance with extra attention to chassis lubrication can effectively prevent similar issues. After all, safety comes first.
