How often should the brake fluid be replaced for an Audi A6?

[MadelineAnn]

Audi A6 should have its brake fluid replaced every 40,000 kilometers or every 2 years. If any abnormalities are detected, immediate action must be taken. The method for replacing brake fluid in an Audi A6 is as follows: 1. First, open the cap of the brake fluid filler port and use a syringe to extract some of the old fluid. After filling with new fluid, lift the car and loosen the brake fluid drain screws near all four tires to allow the brake fluid to slowly drain out. 2. After lowering the car, slowly add new fluid to the filler port to prevent air from entering the brake lines. When only 1/3 of the brake fluid remains in the bottle, quickly raise the car again. 3. Tighten the drain screws on all four tires, then lower the car. Fill the brake fluid reservoir to the top and secure the cap to complete the brake fluid replacement.
