Removing main headlight
ATTENTION: Risk of irreparable damage to electrical and electronic components. Risk of damage to headlights.
- Before removing headlight, remove ignition key an switch off the light.
- Headlights must not be covered, e.g. by wing protector or film, when they are switched on. Risk of damage to headlights due to chaffing and excessive temperatures.
NOTE:
- This description refers to the left headlight, and for a better representation, the illustrations of removal are in sectional view.
- When working, carrying out tests or adjusting headlights on the Cayenne or when it is in the workshop, a battery charging unit with a rated current of at least 40 A must be connected.
- As soon as the vehicle is unlocked, e.g. the vehicle is in the workshop or salesroom, it must be trickle-charged with a battery charging device.
1. Press down on cover -1- in engine compartment and remove it.
2. Push a socket wrench -5- onto the release and unlock in direction of arrow -arrow A- or -arrow B-.
3. The headlight is now unlocked and can be pulled forwards out of the wing.
NOTE: If the Bi-Xenon main headlight is replaced, the gas discharge control unit from the old main headlight must be installed in the new one.
Installing main headlight
NOTE: Before the headlights can be installed, the headlight plug mount for the central headlight plug must be greased with lubricant.
Greasing the plug mount makes it easier for the plug to slide into the mount and thus guarantees an optimal connection.
Use lubricant part no. 000.043.206.16. Since the part number or index is subject to change, the part number must additionally be checked in the PET.
1. Insert headlight into guide rails and push fully home into wing.
2. Press the headlight to the rear, while at the same time turning the socket wrench -5- in the direction of the arrow -arrow A- or -arrow B-. In the process, the headlight lock must engage with an audible and perceptible click.
3. Check that headlight is securely seated, e.g. by pulling gently near the auxiliary high beam headlight.
4. Insert cover -1- and fold over.

Adjusting main headlight
The vehicle must be on a horizontal surface.
Make the adjustment with the regulator switch set to 0 (headlight beam adjustment).
Make the adjustment with the vehicle ready for driving (fuel tank full, driver's seat occupied by a person or 75 kg; the tire pressure must correspond to the specified values) using a headlight adjustment unit.
Bi-Xenon main headlight
NOTE:
- Read out and erase the HBA fault memory before each adjustment of the headlights. To do this in the Porsche System Tester, select the Special functions menu, then select the HBA left menu or the HBA right menu, read out the fault memory, and erase it.
- If a new Bi-Xenon main headlight has been installed, the control unit must also be calibrated for level control before any adjustments are made.
Under menu item "Calibration", the headlight beam adjustment (HBA) control unit is adapted to the current conditions relating to vehicle position. During calibration the existing vehicle position is stored as zero position.
Following calibration, the headlight setting must be checked and corrected if necessary.
Calibration must be performed if changes were made that can change the position of the angle sensors:
- Headlights, complete
- HBA (Bi-Xenon) control unit
- HBA angle sensor (front and rear compression)
- Running gear components
- Damage caused by accidents
NOTE:
- Whenever the coding is changed in the menu item "Change coding", the ignition must always be switched off afterwards and the key removed.
- After the ignition is switched on again, the new coding of the control unit is updated and the stored faults can be erased.
- If the coding does not match the vehicle equipment, faults may be displayed that are not really present.
1. Press down on cover -1- in engine compartment and remove it.
2. Turn on the ignition, turn on dipped beam and high beam headlights.
3. Check setting and adjust if necessary.
Adjusting:
Set headlight adjustment unit to 10 cm/10 m (1%).
NOTE:
- The distance between the headlights and the adjustment unit should be as small as possible.
- It should not exceed 30 cm, because at greater distances it is no longer possible to define the formation of the light/dark limit in the adjustment unit clearly.
- The description refers to the left headlight.
With this alignment, preference must be given to the central zone around the salient point of the light/dark limit.
The vertical/side adjustment of the dipped beam/high beam highlight is carried out first using the flexible screwdriver 9703: adjustment -arrow A- and -arrow B-.
4. To do this, line up the light/dark borderline running upwards at an angle on the right-hand side with the dotted 15 degrees line of the adjustment unit.
5. The dipped beam headlight is then adjusted horizontally using the flexible screwdriver 9703: adjustment -arrow A- and -arrow B-.
NOTE:
- Guide a flexible screwdriver nearly horizontally through the opening in the wing.
- The illustration refers to the halogen headlight.
To do this, line up the left, horizontal section of the light/dark limit (when driving on the right) with the dotted horizontal line of the adjustment unit.
6. Check the auxiliary high beam headlight and, if necessary, adjust the side setting with -arrow A- and -arrow B-. Use the flexible screwdriver 9703 to do this.
7. In the case of Bi-Xenon headlights, the ignition must be switched off and on after the adjustment has been made with the lights switched on.
8. After this, the adjustment must be checked again.
9. Fit cap again.
