Luca,
here you go,

2.8 Liter V6 5V General, Engine (Engine code: AHA, ACK)

Page 19-22

Filling

Notes:

Only use coolant additive G12 (according to TL VW 7745 D). G12 is red in
color.

Do not mix G12 with any other coolant additive!

If the fluid in expansion tank is brown, G12 has been mixed with other
coolant. In this case, the coolant must flushed and replaced.

"G12" and coolant additives marked in accordance with "TL VW 774 D"
prevent frost and corrosion damage, scaling and also raise the boiling
point of the coolant. Therefore, the cooling system must be filled year
round with frost and corrosion protection additives.

A higher boiling point improves engine reliability under heavy load
particularly in countries with tropical climates.

Frost protection additives protect against frost to about -25C (about
-35C in arctic climates).

The coolant concentration must not be reduced by adding water even in
warmer seasons and in warmer countries. The anti-freeze ratio must be at
least 40%.
