How often should the brake fluid be changed for an Audi A3?

Audi A3 brake fluid should be changed every 2 years or 40,000 kilometers, and it is recommended to use the original FAW-Volkswagen brand. The method for changing the brake fluid in an Audi A3 is as follows: 1. Connect the interface of the brake fluid changer to the brake fluid reservoir on the vehicle and tighten it, then turn on the power of the brake fluid changer; 2. Use a lift to raise the vehicle; 3. Loosen the screw of the brake fluid drain port and attach a rubber hose; 4. The process for changing the brake fluid for the front wheels is the same as for the rear wheels. The Audi A3 is a sedan produced by Audi, with body dimensions of 4292 mm in length, 1765 mm in width, and 1423 mm in height.
Speaking of the Audi A3 brake fluid issue, based on my over ten years of driving experience, brake fluid (also called hydraulic fluid) tends to absorb moisture and degrade over time. I recommend replacing it every two years regardless of mileage, especially for those who frequently drive on highways. For my Audi A3 used for city commuting, I visit the dealership every two years for a fluid change and a brake pad inspection. Neglecting this can lead to spongy brakes and slower response due to moisture buildup, increasing the risk of skidding in rainy conditions. Once, I forgot to replace it and nearly rear-ended someone on the highway—that scare prompted me to act immediately. Don’t cut corners here; safety comes first. During the change, the mechanic advised flushing the brake lines too, costing around 500 RMB, which is worthwhile for long-term vehicle health. Remember, don’t just focus on the engine—brake system maintenance is equally critical.
For friends driving an Audi A3, I know a thing or two about cars to share with you. The brake fluid should be replaced approximately every two years. If not replaced, accumulated moisture lowers the boiling point, making emergency braking risky. When I bought the car, the 4S store taught me to use a test pen to check moisture levels—replace if it exceeds the standard. For those who drive frequently, note that high-speed and frequent braking causes faster wear, so it's recommended to replace the fluid every two years or after reaching 40,000 kilometers. Safety isn't something to gamble with—like on rainy days with high humidity, I replace it immediately for steadier braking and peace of mind. Replacing the fluid isn't expensive, just a few hundred bucks, so don't wait for major repairs. During maintenance, check the fluid level and color—replace quickly if it's dark.
