How often should the brake fluid of the Tiguan be replaced?

[HarrisonFitz]

The maintenance manual for the Tiguan specifies that the brake fluid should be replaced every 35,000 kilometers or 48 months. Precautions for using brake fluid are as follows: 1. Do not mix different types or brands of brake fluid, as differing formulations can reduce the performance of the brake fluid. 2. Replace or filter the brake fluid promptly if it absorbs moisture or contains impurities, as this can lead to insufficient braking pressure and affect braking performance. 3. If the vehicle has been driven for 40,000 kilometers or the brake fluid has been in continuous use for over 2 years, it may deteriorate due to prolonged use and should be replaced immediately. 4. If the braking feels inconsistent during normal driving, replace the brake fluid promptly. Before replacement, clean the braking system thoroughly with alcohol. 5. If the vehicle pulls to one side during braking, conduct a comprehensive inspection of the braking system. If the brake cylinder cups are found to be excessively swollen, this may indicate poor-quality brake fluid. In such cases, replace the brake fluid with a higher-quality product and also replace the cups.
