- Open your hood, identify the screws for horizontal and vertical adjustment of the headlights of your Audi A4 (they are in most cases marked, and those on top must adjust the verticality and the one on the side controls the horizontality of the adjustment).
- Use a cloth or another thing to hide the projector on which you are not making the modification.
- Using the screws to make the horizontal modification, you should have the most intense part of the beam which should be a little to the right of the vertical line noted on the wall
- With regard to vertical modification, you will have to use the screw to try to position the upper end of the beam at the level of the horizontal marking on the wall, or slightly below.
- Once finished, check that the headlights setting of your Audi A4 is logical, do not think twice to check it after you have driven it, oftentimes it may move.
