WM, 430115 Calibrating The Levelling System: Checking: Testing
Calibration must be performed if one or more of the following situations apply:
- Control unit was replaced.
- Level sensors were replaced.
The level sensors are calibrated by determining a correction value (corresponding to the actual height of the vehicle) and storing it permanently in the control unit. Select Control unit overview >>Levelling system/PASM<<>>Maintenance/repairs<< Height sensor system calibration on the Porsche System Tester.
Notes
Information
- Prior to calibration, the Normal Level must be adjusted!

- Check that the tire pressure has been set according to the respective tire specifications.
> 43 Calibration
- wheels and tires
- The fault memory must be cleared before starting calibration.
- The vehicle is raised and lowered during the height sensor system component test.
- Do not interrupt calibration! If calibration is interrupted, the fault code 000286 "Customer service mode not complete" is entered. A warning appears in the instrument cluster. If this happens, perform calibration again.
- Select >>Height sensor system component test<< before starting calibration. Select >>Levelling system/PASM<<>>Maintenance/repairs<< Height sensor system component test in the control unit overview using the Porsche System Tester.
- Switch on the air extraction system while the engine is running.
The nominal values for the nominal heights of the level sensors are stored in the control unit (F1 - Help). The actual values of the respective axle heights - front left, front right, rear left, rear right - must be measured manually and then entered using the Porsche System Tester. The actual values must be measured on the front and rear axle, both on the left and right. Also follow the instructions under: - Conditions for carrying out calibration
