Suspension Control Pressure Sensor/Switch: Service and Repair
Replacing sensor (ORS)
Preliminary work for replacing sensor
The ORS sensor is located at the center of the off road stabilizer -arrow- on the front and rear axle respectively.
The procedure for replacing the sensor is the same on both the front and rear axle.
Off road stabilizer sensor
Warning:
Risk of accidents! The off road stabilizer System (ORS) operates at an overpressure of up to 165 bar. Under certain conditions, motions can
occur on the wheel carrier (e.g. if the off road stabilizers are disengaged when lifting, the button is pressed on the center console, and the
wheel carrier is also raised). The anti-roll bar can close quickly.
^
Danger of crushing in the area of the anti-roll bars and wheel carriers. Risk of injury and material damage due to raising the wheel
carrier incorrectly.
-> Before working on the vehicle, ensure that the ORS is engaged. The indicator light on the center console button must be OFF. If the indicator light
is on, follow the following procedure: Switch on the ignition and engage the road driving program >> High Range >>. The anti-roll bars must
engage audibly.
-> Before working on the ORS, always depressurize the system! To do this, connect the PIWIS Tester and select >> Off-road Stabi (ORS) >> Drive
links >> Set FA or RA valve >> in the menu. The valve clocks (audibly) until the procedure is finished.
-> Do not raise the wheel suspension higher than the normal vehicle position (vehicle resting on wheels). When raising the suspension, use a suitable
intermediate layer (hard rubber).
-> Do not damage the brake cover plate.
1. Before starting to work on the off road stabilizer System (ORS), depressurize the system using the PIWIS Tester.
2. Lift the vehicle.
3. Remove engine guard.
Replacing sensor
1. Carefully remove any dirt you see on the sensor's threaded joints (e.g. with a brass wire brush).
