Location

The AIRmatic compressor unit is located on a bracket on the right behind the bumper.

Task

The AIRmatic compressor unit is used to generate the air pressure required to raise the vehicle.

Function

The compressor motor is not actuated directly by the AIRmatic control unit (N51), but rather the load current is switched via the AIRmatic relay (K67). Furthermore, deflating valve is integrated into the AIRmatic compressor unit, and it is used to lower the vehicle level.

If in the event of a fault the pressure in the AIRmatic compressor unit should be too high, then this is automatically reduced by means of an integrated, mechanical pressure relief valve.
