Volkswagen Group vehicles should have their existing brake fluid changed typically at three years and then every 2 years after that.
Brake fluid has a vapour lock point (the temperature at which it boils) of 230 °C, unlike water which boils at 100°C. Brake fluid will absorb moisture over time causing the boiling point to drop rapidly. This moisture can cause the brake fluid to vapourise, meaning your brakes will not be as effective as they should be.
We inspect the brake fluid level and all the hydraulic pipes and hoses. The brake fluid service is carried out using a VW specialist tool, allowing us to drain and replenish the brake fluid. Once complete, we test the system and record the service in your service book.
