Audi A4L windshield washer fluid filler port is located behind the hood hinge on the upper left side of the engine compartment. The washer fluid reservoir in the Audi A4L is situated in the engine compartment with a capacity of approximately 4L. Below is relevant information about the Audi A4L windshield washer system: 1. Cleaning performance: Windshield washer fluid is formulated with multiple surfactants and additives. Surfactants typically possess wetting, penetrating, and solubilizing functions, effectively removing dirt. 2. Antifreeze performance: Containing alcohol and ethylene glycol, it significantly lowers the freezing point of the liquid to prevent freezing and quickly dissolves frost. 3. Anti-fog performance: Forms a monomolecular protective layer on the glass surface. This protective film prevents fog droplet formation, ensuring clear visibility through the windshield.
