Coolant Level, Coolant Level At Least To Upper Mark On Expansion Tank: Notes
There is a risk of injury when the coolant expansion tank being under pressure.
- Only open the coolant expansion tank when the engine is cold.
Incorrect coolant additives may cause significant damage to vehicle components.
- The coolant additive G12EVO is not approved for engines with the base EA288 (TT 2.0L TDI).
The specified value is the upper marking on the coolant expansion tank.
Only distilled water may be used for mixing coolant additives. The water used in the mixture greatly affects the effectiveness of the coolant and the corrosion protection. To meet water quality requirements, only use distilled water when mixing with coolant.
Use only coolant additives according to the Parts Information. Using other coolant additives can impair the corrosion protection. Loss of coolant can cause considerable damage to the engine.
Coolant in the correct mixing ratio prevents freezing and corrosion damage as well as calcification. The boiling temperature is also increased. For these reasons the cooling system must have coolant additive the whole year.
Coolant cannot be reused.
Only use water/coolant additive as lubricant for the coolant hoses.
Driving the vehicle with the coolant level above the upper mark on the coolant expansion tank is a technical requirement and is permitted. Do not extract the coolant!
Operating a vehicle with a coolant level under the upper mark is not permitted.
