1.5.2 Filling

Note
When mixing the coolant, only used demineralised or distilled
water to standard VDE 0510. Tap water must no longer be
used!
Note
The water used in the coolant mixture has a great influence on
its effectiveness. Because the water quality differs from country
to country and even region to region, Volkswagen has decided
to define the quality of the water to be used in the coolant sys-
tem. Distilled water fulfils all requirements. It is therefore recom-
mended that distilled water be mixed with the coolant whenever
an older model's coolant is replenished or replaced. For newer
engines (model year 2010 ►) the use of distilled water is abso-
lutely essential and compulsory.
