How to adjust the headlights of a Polo?

The steps to adjust the headlights of a Polo are as follows: 1. It is best to drive the car to a less crowded place, preferably at night. 2. Prepare a 6mm hex wrench, start by adjusting the low beam, then adjust the high beam distance. 3. When adjusting, slowly turn the wrench, avoiding large adjustments at once to prevent stripping the threads. The detailed steps for adjusting the headlights are as follows: 1. After turning on the high beams, stand in front of the headlights with your feet as close to the headlights as possible, observe the position where the high beams shine on your feet, and note the center of the light (the brightest spot of the beam). 2. Then move vertically to a wall (without deviating), and mark the position of the light center on the wall based on the position on your feet. 3. Use a screwdriver to rotate the headlight's adjustment gear, ensuring the light center aligns with the mark you made on the wall (the vertical distance should not exceed 10 cm). 4. If there is no one else in the car while adjusting the lights, you can slightly raise the light center (generally no more than 5 cm). The reason is simple: an empty car sits higher, and when loaded, the car will settle slightly. Raising the light center slightly allows for some adjustment margin. 5. Adjusting up and down will show obvious movement of the light center, while adjusting left and right may not be as noticeable. It may take several turns to see slight movement, so don’t worry if the light center doesn’t move left or right immediately—keep turning the screwdriver until the light center aligns with the mark. 6. Once both headlights' light centers are aligned with the marks, stand in front of the car (a bit farther away) and observe the beam pattern. At night, with the high beams on, it’s easy to see if the beams are pointing straight forward, as there might have been some deviation when marking the wall.
As a Polo owner who has driven it for several years, I've personally adjusted the headlights. The key is to locate the white plastic adjustment screws behind the headlight assembly under the hood - usually one controls vertical alignment and the other handles horizontal alignment. Park the car 7-8 meters away from a flat wall, turn on the low beams to project onto the wall. Use a Phillips screwdriver to slowly turn the adjustment screws until the brightest point of the light beam is slightly below the center height of the headlight. I recommend having a friend assist - one person turns the screws while the other observes the light position for greater precision. After adjustment, remember to test the road illumination effect with a nighttime drive.
Headlight adjustment is crucial for nighttime driving safety and should never be taken lightly. Before adjusting, it's best to place a smartphone level on the engine cover to ensure the vehicle is completely level. Prepare a long-handled Phillips screwdriver, as the adjustment holes on the Polo are quite deep. When adjusting left and right, first check if the lights are symmetrical, then adjust each headlight separately. For height adjustment, ensure the main beam doesn't dazzle oncoming drivers. If the wall reflection is unclear, use tape to mark the standard height line. After adjustment, always conduct a road test to confirm the proper illumination distance and width.
Adjusting the Polo's headlights yourself is actually quite simple and can be done in half an hour over the weekend. First, find a flat wall in an underground garage as a reference, then back the car up to about 5 meters from the wall. Open the hood and locate the two cross-slotted knobs at the rear of the headlights: the outer one adjusts height, while the inner one controls the left-right direction. Loosening the fuse box in front of the steering wheel makes the operation more convenient. Rotate each knob a quarter turn at a time to test the changes until the light focus falls slightly below the center of the headlight. Be careful not to apply too much force and break the plastic parts, and wearing gloves throughout the process is safer.
