Integral Active Steering: Servotronic

Both the base steering and Integral Active Steering have Servotronic. The speed-dependent steering servo is implemented by the Servotronic valve on the steering box. The Servotronic valve is always controlled by the ICM control unit. This means that the ICM control unit also contains the logic of the Servotronic function.

The ICM control unit also activates the ECO valve. This valve enables electronic adjustment of the volumetric flow of the power steering pump.
