Use the wiper operation knob to first spray out the old windshield washer fluid. 2. After spraying out the existing fluid, open the windshield washer fluid filler port and add a small amount of new windshield washer solution. 3.

Having driven my Audi A4L for many years, I've noticed that the windshield washer fluid reservoir is located on the left side of the engine bay. After popping the hood, you can easily spot a small blue cap marked with a windshield and wiper icon—just twist it gently to open. I always refill it during weekend garage parking sessions using dedicated automotive washer fluid, never tap water, as its impurities can clog the nozzles. Before each top-up, I make sure the engine is thoroughly cooled to avoid burns from hot components—simple and safe. Maintaining this routine for years has kept my wiper system trouble-free, ensuring clear visibility and driving confidence. I recommend checking the fluid level weekly during car washes—it’s efficient, worry-free, and extends part longevity.
