If a new angle sensor has been installed for headlight beam adjustment (HBA), the headlights must be recalibrated with the Porsche System Tester.

Calibrating angle sensor for headlight beam adjustment
With the vehicle standing on level ground:
1. Connect the Porsche System Tester to the vehicle and start the System Tester. Switch on ignition.
2. Select "Special function" using the cursor keys.
3. Select "- HBA left or right -" using the cursor keys.

Under the menu item "Calibration", the control unit for the gas-discharge lamp is adapted to current positional conditions in the vehicle. The existing vehicle position is stored as zero position during calibration.

Following calibration, the headlight setting must be checked and corrected if necessary.

4. Read out fault memory. If fault is present, proceed in accordance with Headlight beam adjustment diagnosis.
5. Check headlight setting.
