Fuel, Exhaust and Engine Electrics

Fuel Supply, Low-pressure Side


Crankcase ventilation

Crankcase ventilation also takes place into the intake system.
- On the naturally aspirated engine, this takes place on the left of the electronic throttle directly into the intake manifold (and on the turbo engine if no boost pressure is present).
- On the turbo engine with boost pressure, ventilation takes place to the intake side of the left turbocharger.

The entry point directly on the intake manifold has an electric heater to prevent freezing at corresponding temperatures and to therefore avoid the risk of excess pressure in the crankcase.
