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.

Damping adjustment valve - N337 front right


-1- Connector for damping adjustment valve -N337


-2- G342 Body acceleration sender



-3- Connector for G342  


- The valve is built into the suspension strut.

- The connecting cable of the magnetic

coil is routed through the hollow piston

rod to the outside.


- The lowest damping force is when a current of approx. 1800mA is applied to the magnetic coil.


- The highest damping force is

when there is no electrical activation of the magnetic coil.


- Emergency running: There is no activation

of the magnetic coil. Then the max. damping force is set, thereby ensuring stable ride dynamics.
