Is it normal for the windshield wiper to make a noise when the Tiguan L starts?

[LeKinsley]

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.

Don't panic over the initial wiper noise on the Tiguan L in most cases. I've observed this vehicle's wiper system features a startup detection mechanism - a slight sound may occur during power-on as the motor automatically resets, which is part of the circuit design. However, it shouldn't be completely ignored. Last time my car produced unusually harsh noises, which turned out to be caused by loose wiper arm mounting screws creating vibration; tightening them for 10 minutes solved it. I recommend performing simple checks first: look for stubborn stains rubbing against the blades, cracked wiper inserts, or overly tight springs - these details can prevent noise escalation. If the sound progressively worsens or comes with intermittent stoppages, immediately inspect the motor and relay to avoid being stranded during rain. When parking, try to avoid prolonged sun exposure to delay rubber component hardening.

The wiper makes a noise when starting? This is quite common with the Tiguan L. My car does the same thing—the wiper gives a slight sound when first starting up, but it doesn’t affect anything. Don’t rush to the repair shop; it’s probably just the factory-set self-check program activating. Try pressing the washer nozzle a few times before a cold start to spray some fluid and moisten the rubber blade—sometimes the friction sound from dry wiping gets masked. Remember to replace the wiper blades after the rainy season, as aged blades can squeak even more annoyingly. Simple actions can reduce most of the noise.

The initial squeaking noise of the Tiguan L's wipers may sound trivial, but it's no small matter. Once, I ignored the abnormal sound during a long drive, and the wipers ended up jerking erratically in heavy rain, nearly obscuring my view. I've since learned my lesson—now I pay attention to the sound frequency every time I start them: a brief click is normal for the reset action, but if there's a rattling sound lasting two to three seconds, it could indicate rust on the wiper linkage or unstable battery voltage interfering with the control module. Regularly pop the hood to check the elasticity of the wiper arm springs and inspect for rust at the base, applying some anti-rust oil for maintenance. It's best to test the wipers before rain hits to ensure they won't fail when you need them most. Safety should always be a top priority.

My friend who drives a Tiguan L always complains about the wiper noise at startup. I told him it's normal self-checking and not to worry. Some car models are programmed to have the wipers move slightly upon ignition to clear debris from the windshield, especially in northern areas with more tree sap and willow catkins, as the system automatically prevents buildup. However, it's important to distinguish abnormal situations: if the noise is particularly loud during humid or overcast weather, it might be due to a deformed wiper arm failing to press the rubber strip properly or increased friction caused by windshield oil film. It's recommended to use a dedicated cleaner to remove the oil film and check the lubrication of the wiper linkage bearings. This topic also brought up the sensitivity of wiper frequency settings—adjusting the automatic mode to medium or low speed can reduce startup noise.
