Audi A4L's windshield washer fluid reservoir is located at the rear side of the engine hood pressure rod, with a washer symbol on the cap. To refill windshield washer fluid for Audi A4L, follow these steps: 1. Use the wiper control knob to spray out the old fluid first. After completely emptying the existing fluid, open the washer fluid filler port and add a small amount of new washer fluid solution. 2. Activate the washer spray switch again to flush out any remaining old fluid. 3. When no more fluid sprays from the nozzles during the second activation, add approximately 4L of new washer fluid, then securely close the cap.
