How do I adjust the headlight beam on my Audi A2?

My Audi A2 has been having uneven lighting and I suspect the headlight beam needs adjusting. How do I do this myself?

First, park your car on a flat surface facing a wall. Turn on the headlights and adjust the beam alignment with the screw located on the back of the headlight housing. Use a screwdriver to turn it clockwise or counterclockwise until the beam is level with the wall.

If the headlight beam is still uneven, use a level to ensure the car is on a level surface and adjust the screw on the side of the housing for vertical alignment. You may need to repeat this several times to get it just right.

Make sure to check the headlight washers and adjust them if necessary. Often, uneven headlight beams are caused by blocked or misaligned washers. Use a needle or toothpick to clean any debris that may be blocking the nozzle.
