Refill only with distilled water. All other types of water can cause corrosion in the engine due to 
the chemical components contained in the water. This can also lead to engine failure. If any other 
type of water apart from distilled water has been refilled, the fluid in the cooling system should be 
completely replaced immediately by a qualified workshop.

Brake fluid 
 
Fig. 190 In the engine compartment: cap on the brake fluid reservoir. 
Brake fluid will gradually absorb water from the surrounding air over the course of time. The brake 
system will be damaged if there is too much water in the brake fluid. The boiling point of the brake 
fluid is also considerably reduced by the water content. Heavy use of the brakes and full braking may 
cause a vapour lock in the brake system if the water content is too high. Vapour locks reduce levels 
of braking power, considerably increase braking distance and can even cause the brake system to fail 
completely. Your own safety and that of other road users depends on having a brake system that 
functions properly at all times  
Brake fluid specification 
Volkswagen has developed a brake fluid that has been optimised for the brake system in the vehicle. 
To ensure optimal operation of the brake system, Volkswagen expressly recommends the use of 
brake fluid compliant with VW standard 501 14. 
Before using a particular brake fluid, check that the brake fluid specifications printed on the 
container correspond to the vehicle requirements.
