Steering: Description and Operation
The Servotronic electrically controls the steering power assist relative to vehicle speed. If the electronics malfunction, the regular power steering system operates normally, although two different characteristics can be noted:
^ Greater than usual force is required when steering the vehicle, e.g. turning into a parking space
^ The steering is unusually easy to move at high vehicle speed
If the steering is hard to turn to only one side (i.e. steering to the right easily and steering to the left hard) there is a hydraulic malfunction. The steering gear must be replaced.
