The Valvetronic Control Module Is Assigned (Programming) To The Appropriate Engine And ECM By The DISplus.

The Idle Speed Control  is also regulated by the Valvetronic system. Reduced valve lift when the engine is idling ensures that the engine receives the appropriate airflow. When the Valvetronic system is in use, the idle speed control and intake manifold vacuum is also regulated using the electronic throttle valve.

During the starting procedure at a temperature of between 20 °C and 60 °C, airflow is controlled by the throttle valve. If the engine is at operating temperature, it will be switched to non-throttle mode approximately 60 seconds after it is started up.

At temperatures below 20 °C, the engine is started with the throttle valve fully opened using the Valvetronic for idle speed control (this has a positive effect on the starting characteristics).
