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

[McAvery]

Audi A6 brake fluid should be changed every 2 years or 40,000 kilometers. The method for changing the 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 the four tires to allow the brake fluid to slowly drain out. 2. Lower the car and slowly add new fluid to the filler port to avoid air entering the brake lines. When only 1/3 of the brake fluid remains in the reservoir, quickly lift the car again. 3. Tighten the drain screws on all four tires and then lower the car. Fill the brake fluid reservoir to the top and secure the cap to complete the brake fluid change. When using brake fluid, note that different types and brands of brake fluid should not be mixed. If the fluid absorbs moisture or contains impurities, it should be replaced or filtered promptly; otherwise, it may lead to insufficient braking pressure and affect braking performance. If the vehicle's braking shows signs of pulling to one side, it is advisable to replace the brake fluid with a higher-quality product.
