Actuators

Logic of naming actuators in VW-group is simple it contains "N" + actuator number. The actuator number is unique. Here you can find fitting location, connectors and some basic information about actuators.

To our mind, actuators information is reference, so there is only simple search by number.

J The damper is switched to hard if a current of approx. 1A is applied to the damper coil.

 

J The damper is switched to soft if a current of approx. 300mA is applied to the damper coil.

 

YZ Emergency running: If the damper control fails (such as because of a defective control unit) a steel spring is detected. The damper control is then as in the case of a soft set-up.

This ensures stability of driving dynamics.
