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

Audi A6 brake fluid should be replaced every 2 years or 40,000 kilometers. Brake fluid is a liquid medium used in hydraulic braking systems to transmit braking pressure, employed in vehicles with hydraulic braking systems. Taking the 2004 Audi A6 as an example, its body dimensions are: length 4886 mm, width 1810 mm, height 1475 mm, wheelbase 2850 mm, minimum ground clearance 115 mm, and fuel tank capacity 70 liters. The 2004 Audi A6 is equipped with a 1.8T turbocharged engine, with a maximum power of 110 kW and a maximum torque of 210 Nm, paired with a 5-speed automatic transmission.

I've been driving an Audi A6 for several years, and the brake fluid is generally changed every two years or every 40,000 kilometers, depending on driving habits and road conditions. If you frequently encounter city traffic jams or drive long distances, the braking system is under greater pressure, and the fluid is more prone to absorbing moisture and deteriorating, leading to reduced braking performance. Last time, I delayed changing it until 50,000 kilometers, and the brakes felt spongy—almost causing an accident. After replacing the fluid at the 4S店, the responsiveness immediately improved. I recommend regularly checking the fluid color; if it darkens or has impurities, change it early. Don't skimp on this—safety comes first. Just have it done at a professional shop.

As a car enthusiast, I've studied the Audi A6's braking system. Brake fluid is highly hygroscopic, and over time its boiling point decreases, potentially causing failure during emergency braking due to vaporization. The manufacturer recommends replacement every two years or 40,000 kilometers, but in practice, the interval should be shorter if frequently driving in humid areas or with aggressive driving habits. I use a moisture test pen to check water content and replace if it exceeds standards. The replacement process requires professional equipment to bleed air bubbles, otherwise braking performance may be affected. Neglecting this could lead to pump damage or accidents - spending a few hundred on maintenance is far more economical than major repairs.

I'm quite frugal, so when driving an Audi A6, I try to follow the manual's recommendation of changing the brake fluid every two years or 40,000 kilometers, but I always shop around for the best deals. Dealerships are expensive, while reliable repair shops are cheaper, but DIY is too risky and not recommended. I usually pay attention to any abnormal brake noises or a soft pedal and check the fluid condition in advance. If the fluid is clear, I might delay the change slightly, but never exceed 50,000 kilometers. Saving money shouldn’t compromise safety—regular maintenance can extend the life of brake pads and avoid major repairs.
