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 -N336 front left

- The valve is built into the suspension strut.


-1- Damping adjustment valve

-2- Connector for damping adjustment valve


- The lowest damping force is when a current of approx. 650mA is applied to the solenoid.


- The highest damping force is

when a current of about 2000 mA is applied to the solenoid


- Emergency running: There is no activation

of the solenoid.

The damping force corresponds to a mean value (caused by the pre-tension of the springs).

This means stable driving dynamics are safeguarded even if the damper control fails.
