Notes on calibration

Information 

• Calibration can only be carried out while the vehicle is stationary. 
• The vehicle must stand "floating" on the measuring platform to avoid straining the axles. 
• Calibration is also required for the variants with "steel springs - PASM". The headlight beam adjustment (HBA) sensors are also calibrated. 
• Prior to calibration, the vehicle must be set to Normal Level! 
• Ensure that tyre pressures have been adjusted to the respective tyre specifications. (>>4405IN Wheels and tyres) 
• The vehicle is raised and lowered during the height sensor system component test and then adjusts to the correct level! 
• The measured values for the vehicle height must correspond approximately to the values specified under Adjustment values for suspension alignment. An implausible value will not be accepted. For the current comparative values for the vehicle height, please refer to the adjustment values for suspension alignment →  WM 449503 Suspension alignment, complete 
• Do not interrupt calibration! If calibration is interrupted, the fault code 000286 "Customer service mode not complete" remains stored and is active! A warning appears in the instrument cluster. Select << >>Completion of height sensor calibration<< in the Drive links/Tests menu. Erase the fault memory and perform calibration again! 

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 using the Porsche System Tester. The actual values must be measured on the two axle carriers (front axle, rear axle), both on the left and right. → WM 4301K2 CALIBRATION
