Where to Add Windshield Washer Fluid in A4L?
1 Answers
The windshield washer fluid reservoir in the Audi A4L is located on the rear side of the engine hood pressure strut, with a cap marked with a washer symbol. The capacity of the windshield washer fluid in the Audi A4L is 5L, and it should be refilled appropriately based on the remaining amount. Windshield washer fluid is a consumable item and does not have a fixed refill cycle; it depends on the frequency of use by the owner. When adding windshield washer fluid, the following points should be noted: Only professional windshield washer fluid should be used in cars; tap water cannot be used as a substitute. This is because windshield washer fluid not only cleans but also has anti-static and lubricating functions. In winter, it also provides antifreeze and anti-fog effects, which tap water cannot achieve. If you are in a remote area and run out of windshield washer fluid, you can temporarily use mineral water as a substitute. Although mineral water is still far inferior to windshield washer fluid, it is better than tap water as it contains no impurities. Windshield washer fluid has the following properties: Cleaning performance: Windshield washer fluid is composed of various surfactants and additives. Surfactants typically have wetting, penetrating, and solubilizing functions, thereby aiding in cleaning and removing dirt. Antifreeze performance: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, providing antifreeze effects and quickly dissolving frost. Anti-fog performance: A single-molecule protective layer forms on the glass surface. This protective film prevents the formation of fog droplets, ensuring the windshield remains clear and transparent for optimal visibility. Lubrication performance: Windshield washer fluid contains ethylene glycol, which has a high viscosity and provides lubrication, reducing friction between the wiper blades and the glass to prevent scratches. Anti-corrosion performance: Windshield washer fluid contains various corrosion inhibitors, ensuring it does not corrode any metals and is completely safe for car paint and rubber.
