MODEL 164.1/8 with CODE (489) Airmatic (air suspension with level adjustment and adaptive damping system ADS) up to Model Year 8
MODEL 164.8 with CODE (489) AIRmatic (air suspension with level adjustment without ADS adaptive damping system) with CODE (494) USA version up to Model Year 8
Shown on model 164.1
Location
The AIRmatic pressure sensor is located in the AIRmatic valve unit (Y36), which is located on a bracket behind the right bumper.
Task
The AIRmatic pressure sensor records the system pressure and the central reservoir pressure as a priority.
It is used for plausibility checks.
With selected actuation of the individual valves in the suspension struts the pressure of each individual suspension strut can be measured by the AIRmatic pressure sensor.
Example: To record the pressure in the left front suspension strut, the AIRmatic compressor unit (A9/1) must be switched off, the AIRmatic pressure reduction valve (A9/1y1) closed, the AIRmatic central reservoir charge valve (Y36y5) closed and the valve of the left front suspension strut opened.
