The brake fluid reservoir is located in the engine compartment on the left.
Note: On right-hand drive vehicles, the brake fluid reservoir is on the opposite side (right) side of the engine compartment.
Level check
The brake fluid level must be between the minimum and maximum marks printed on the translucent wall of the reservoir. A gradual, slight drop in level during operation due to brake pad wear is normal.
If the brake fluid level has dropped significantly in a short time or dropped beyond the minimum mark, this indicates a violation of the tightness of the brake system and leakage of brake fluid. At too low level of a brake liquid the control lamp lights up. In the event of a brake fluid leak, immediately contact a service station to check and repair the brake system.
Brake Fluid Replacement
Brake fluid is hygroscopic, meaning it absorbs moisture from the surrounding air over time. Too high a water content in the brake fluid can cause damage to parts of the brake system from corrosion. In addition, the boiling point of the brake fluid is significantly reduced. Therefore, every two years the brake fluid must be changed!
Attention: Due to the decrease in the boiling point of the old brake fluid, when the brakes are heavily loaded, vapor locks can form in the hydraulic system; in this case, the braking efficiency drops sharply and unexpectedly.
Use brake fluid recommended by Volkswagen (specification FMVSS 116 DOT 4), which must be new and packed in a hermetically sealed container.
Caution: Brake fluid is poisonous! Keep it in a tightly closed container and keep out of the reach of children. Also, remember that brake fluid will eat away at your car's paintwork.
Changing brake fluid requires special tools and skills, so it is best to have it done at a service station.
It is recommended to change the brake fluid as part of the periodic maintenance (service work).
