Off-Road Stabilizer System (ORS) - Checking fluid level
Procedure for checking fluid level





Disengaging and engaging the Offroad stabilizer





Note:
^ Before the fluid level is checked, the Offroad stabilizer must be >> disengaged and engaged << four times.
^ To obtain a correct measured result, it is necessary to depressurize the system. Only then will the correct fluid level be displayed.

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





2. Activate the Offroad stabilizer button four times. The indicator light -arrow- comes on. Only initiate the next switching operation when the off-road stabilizer has >> disengaged or engaged << audibly.
3. Switch off the off-road driving program >> Low Range << again.

Depressurizing the Offroad Stabilizer System (ORS)





1. Connect the Porsche System Tester and switch on the ignition.
Switch off the off-road driving program >> Low Range <<. To do this, use the rocker on the center console -direction arrow- to select the corresponding driving program. The indicator light -arrow- must be OFF. In the menu, select >> Offroad Stabi (ORS) >> Drive links >> Clock valve VA or valve HA <<.
2. The solenoid valve clocks (audibly) until the overpressure has been equalized. The fluid level in the reservoir of control unit C of the Offroad stabilizer 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 in the next chapter.
5. Unplug 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
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 -arrow-, rear left, in the center of the D-pillar. Remove the cover.





2. The dipstick -arrow- 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. mark.





4. The off-road stabilizer system is filled with Pentosin CHF 11S using the - dipstick opening.
5. After the work is completed, insert the dipstick and fit the cover.
