NOTE:

All engines from MY 2008 are filled with coolant additive G12 Plus Plus (purple color). Due to the positive properties, fill only with G12 Plus Plus. Do not add G12 Plus. It will cancel out the advantages provided by G12 Plus.

All engines through MY 2007 are filled with coolant additive G12 Plus in accordance with TL VW 774 F (purple color). Only use G12 Plus or G12 Plus Plus because of its advantages.

The coolant additive G12 Plus Plus protects the entire cooling system better from corrosion and reduces the danger of the sludge and corrosion.

G 12 Plus Plus is a permanent fill for cast iron and all-aluminum engines and gives optimum protection against freezing, corrosion damage, scaling and overheating.

G 12 Plus Plus increases the boiling point to 275 °F (135 °C) and ensures better heat dissipation.

The coolant portion of the mixture must amount to at least 40% (freeze protection down to -13°F (-25°C)) and should not exceed 60% (freeze protection down to -40°C). Otherwise the freeze protection will be reduced and the cooling efficiency will be worsened.

The freeze protection must be ensured down to approximately -13°F (-25°C).
