What Causes the Bumpy Noise in Audi A3?
1 Answers
It could be an issue with the differential or a problem with the suspension. You can have it checked at a 4S shop. You can perform the following self-inspection for bumpy noise: Lift the car to check if the chassis is loose, inspect whether the shock absorber top mount is loose, and check if the shock absorber is damaged. Daily maintenance for cars: Regularly check if antifreeze, brake fluid, and windshield washer fluid are sufficient. Perform wheel alignment periodically. Regularly inspect the wear level of brake pads and clutch plates. Check and replace engine oil promptly. Clean the car regularly. When driving or parked, the car is prone to accumulating dust particles, bird droppings, etc., especially after rain. Over time, the acidic substances in these can corrode the car's paint surface, leading to a loss of shine and, in severe cases, color fading.
