Notes on calibration
Note. Prior to calibration, the normal level must be adjusted! --> Conditions for carrying out calibration . Ensure that tire pressures have been adjusted to the respective tire specifications. Refer to 44 IN TIRES - AS OF MY 2003 (ALL MODELS) . During calibration, the vehicle is raised and lowered! When engine is running, switch air extraction system on. The security code is displayed in the Porsche System Tester under menu >> Level adjustment >> Actual values.
The nominal values for the nominal heights of the level sensors are stored in the control unit. The actual values of the respective axle heights, front left, front right, rear left, rear right, have to be measured manually and then entered with the Porsche System Tester. The actual values are to be measured on the two axle supports (front axle, rear axle), both on the right and left. --> Conditions for carrying out calibration .
Scheme 2
The distance (middle of wheel) between the road (wheel contact area on measuring platform) and the measuring point -A- on the axle support is measured. (Scheme 2)
