BMW 3 Series Wiper Abnormal Noise?
2 Answers
Uneven wiper blades can lead to deformation and abnormal noise when frequently used during rainy days. Extended information regarding wiper abnormal noise is as follows: 1. Presence of impurities or foreign objects on the wiper blade or glass surface: The wiper encounters significantly increased resistance at certain positions, causing shaking. 2. Aging or hardening of the wiper blade: The wiper becomes aged or hardened, resulting in poor contact with the glass. 3. Improper contact surface between the wiper and the glass: Some rubber strips are heavily pressed against the surface while others bear little force, leading to uneven force distribution during wiper movement, which causes certain parts of the wiper to shake. 4. Wear on the wiper blade edge: The wiper arm and pivot shaft are not securely fixed or are improperly positioned, causing the wiper blade to contact the lower part of the windshield, resulting in shaking and abnormal noise. This can be resolved by adjusting the position of the arm. It could also be due to the arm not being completely parallel to the windshield.
My BMW 3 Series had been making squeaky noises with the wipers recently, especially on rainy days, which was quite annoying. I thought about it, and there could be several reasons, such as the wiper blades being worn out or dirty. Once, I pulled over and wiped the edges of the wiper blades with a tissue, finding tree sap and dust stuck to them. After cleaning, the noise reduced. Another reason could be oil film or impurities on the windshield. The front windshield of a BMW 3 Series tends to accumulate oil stains, especially after driving in the city for a while. I bought a professional glass cleaner, sprayed it on, and rinsed it off with water—it worked well. But if the noise persists, it’s worth checking if the wiper arm is installed at the correct angle. BMW’s design is quite precise, and if the angle is off, it can cause uneven wear on the rubber. In winter, extra care is needed because if the wiper blades freeze and harden, they can produce a screeching sound. I replaced them with new, genuine BMW wiper blades, and the problem was solved. Regular maintenance is crucial—inspecting the wiper system every six months can prevent such issues and avoid compromising driving visibility.
