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

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. After lowering the car, 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 bottle, quickly lift the car again. 3. Tighten the drain screws on all four tires, then lower the car. Fill the brake fluid reservoir, secure the cap, and the brake fluid change is complete. When using brake fluid, note that different types and brands of brake fluid should not be mixed. If the brake 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 is uneven, choose a higher-quality brake fluid for replacement.
I've been driving an Audi A6 for almost ten years, and brake fluid is something that basically needs to be changed every two years. The Audi manual usually specifies two years or 20,000 kilometers, but in actual driving, it depends on the road conditions and your driving habits. Brake fluid gradually absorbs moisture, and the more moisture it contains, the lower its boiling point becomes. If you slam on the brakes at high speed, the brakes might fail, which is quite dangerous. I once almost had a collision because I didn’t change the fluid on time. Since then, I’ve made it a habit to use a moisture test pen to check the water content every 15,000 kilometers or so. If it exceeds the limit, I change it immediately. My advice is not to delay—get it done on time at a reputable shop to ensure safety. Audi parts are quite particular, so it’s best to use genuine factory fluid to avoid corroding the system. Remember, this isn’t something to skimp on—safety comes first.
