Engine type

Using engine oil that is compliant with the VW

504 00 standard instead of VW 508 00

Engine oil additives

No type of additive should be mixed with the

engine oil. The deterioration caused by these

additives is not covered by the warranty.

If the recommended engine oil is not availa-

ble, in the event of an emergency you can

change the oil once with a maximum of 0.5 L

of the next oil until the next oil change:

–

Petrol engines: standard VW 504 00,

VW 502 00, VW 508 00, ACEA C3 or

API SN.

–

Diesel engines: standard VW 507 00,

VW 505 01, ACEA C3 or API CK-4.

The essentials

even in warm climates where anti-freeze pro-

tection is not required.

Coolant

Brake fluid

If for weather reasons further protection is

necessary, the proportion of additive may be

increased, but only up to 60 %; otherwise an-

tifreeze protection will diminish and this will

worsen cooling.

When the coolant is topped up, use a mixture

of distilled water and at least 40 % of the

G13 or G12 plus-plus (TL-VW 774 G) additive

(both are purple) to obtain an optimum anti-

corrosion protection

The engine cooling system is supplied from

the factory with a specially treated mixture of

water and at least 40 % of the additive G13

(TL-VW 774 J), purple. This mixture gives the

necessary frost protection down to -25°C

(-13°F) and protects the light alloy parts of

the engine cooling system against corrosion.

It also prevents scaling and considerably rai-
