WARNING: This page is about a different car, the 2011 BMW 750xi, 2011 BMW 750Lxi, 2010 BMW 750xi, and 2010 BMW 750Lxi. However, it is still accessible from the selected car via links, so may be relevant.

The expansion tank of the cooling system for the charge air cooler must be empty.
There must be sufficiently premixed coolant in the filling unit container, 1 - 2 liters more than the vehicle filling capacity.
- Use only approved COOLANT .
- Observe mixture ratio: 50% antifreeze and 50% water. In severely cold areas, the antifreeze can be increased to 60% which provides freezing protection down to-62°F (-52°C). Do not exceed a 60% ratio of antifreeze.
- Observe capacities.
Position the filling unit container at the same height as the coolant expansion tank.
Compressed-air connection with 6 bar pressure present.
Set heating to maximum temperature.
