Is it normal for the windshield wiper to make a noise when the Tiguan L starts?
2 Answers
Tiguan L's windshield wiper making a noise upon starting is a normal phenomenon. Here are some precautions for using windshield wipers: 1. Maintain cleanliness: When there are streak marks on the glass surface, the wiper blade may be dirty. You can sprinkle alcohol on a towel and wipe the surface of the wiper blade. Cleaning it once a month can improve the wiper's performance. 2. Check the rubber: If the wiper makes unusual noises while operating, the rubber blade may be aged or cracked. If the wear is not severe, you can use sandpaper to smooth out rough spots on the surface. 3. Avoid sunlight: Park the car in a shaded area away from direct sunlight, such as a garage. Summer is particularly harsh on cars. Wiper blades are rubber products, and exposure to sunlight will only accelerate their aging. 4. Refill fluid: Adding plain water directly to the windshield washer fluid reservoir is not conducive to the long-term maintenance of the windshield and wiper blades. To ensure the longevity of the components, always use proper windshield washer fluid. Refill the washer fluid promptly to be prepared for unexpected needs.
I've been driving the Tiguan L for almost two years now, and I often encounter the wiper making a brief noise during startup. When the car was new, I thought it was a defect and specifically went to the 4S dealership to ask about it. The technician explained that this is the wiper's self-check function—the motor briefly operates to check the system status, similar to a computer's boot-up self-test. This is especially common in models with automatic rain-sensing features, where sensor initialization slightly triggers the motor, which is completely normal. When washing the car, pay attention to wiping the edges of the wiper blades with a wet cloth to remove dust and dirt, preventing them from aging, drying out, and making strange noises. Additionally, after using the wipers in rainy weather, it's best to return them to their original position before turning off the engine—this will make the startup noise quieter next time. By developing regular maintenance habits, you generally don’t need to worry about them failing.
