Stabilizer Bar: Testing and Inspection

WM 0X03IN Hydraulically disengagable off-road stabiliser - checking fluid level and operation

Checking

Disengaging and engaging off-road stabiliser

Information

- Before the fluid level is checked, faultless operation must be ensured. >> Disengage and engage << the off-road stabiliser four times. The off-road stabiliser must shift audibly.

1. To do this, switch on the ignition and engage the Low Range off-road driving program. Press the brake pedal and briefly press the -rocker switch (direction arrow)- forwards; the -indicator light (arrow)- comes on.

2. Press the -off-road stabiliser button- four times. The -indicator light (arrow)- comes on. Only trigger the next switching operation when the off-road stabiliser has audibly >> disengaged or engaged <<.

3. Switch off the >> Low Range << off-road driving program again.

Depressurising the off-road stabiliser system (ORS)

Information

- To obtain a correct measured result, the system must be depressurised. Only then will the correct fluid level be displayed.

1. Connect the Porsche System Tester and switch on the ignition. Switch off the >> Low Range << off-road driving program. To do this, use the -rocker switch on centre console (direction arrow)- to select the appropriate driving program.
The -indicator light (arrow)- must be OFF.
In the menu >> off-road Stabi (ORS) >> Drive links, select >> Clock front-axle valve or rear-axle valve .

2. The solenoid valve clocks (audibly) until the overpressure has been compensated. The fluid level in the reservoir of -control mechanism C- of the offroad stabiliser rises.

3. The valve no longer clocks. Now the correct fluid level can be read on the dipstick.
4. Reading and correcting the fluid level is described.
5. Disconnect the Porsche System Tester. After switching on the ignition again and engaging Low Range, the system adjusts automatically to the correct pressure.

Reading and correcting the fluid level

Front stabiliser (switched)

The reservoir is not freely accessible. It is filled using the dipstick opening. To do this, refill the amount of fluid necessary using suitable filling equipment. Pull out the dipstick several times and check the fluid level.
1. The dipstick is accessible below the upper cover -cover (arrow)- , rear left, in the centre of the D-pillar. Remove the cover.

2. The dipstick -dipstick (arrow)- is inserted in the left D-pillar. Pull out the dipstick.

3. The fluid level must be between the -markings on the dipstick-. Do not top up above the Max. marking.

5. The off-road stabiliser system is filled with Pentosin CHF 11S through the -dipstick opening-.

6. After the work is completed, insert the dipstick and fit the cover.
