Adjusting the high beams of your Audi S4 for safety

Another legislation supervises their use, the European one (directive 76/756/EEC), which stipulates that there is no maximum height for the adjustment of the headlights, but that the maximum width of the beam must be identical to that of the dipped headlights and that the maximum luminosity must be 225, 000 cd.

The headlight adjustment of his Audi S4

Once your vehicle is in position, you will turn on your dipped beam and make a cross-shaped mark (one horizontal and one vertical section) in the middle of the beam that will be projected on the wall. Check with a level that both parts of the cross are horizontal. Then back your car up to a distance of between 7 and 10 metres. For the rest of the process here are the steps to stick to:

  • Open your bonnet, identify the screws for horizontal and vertical modification of the headlights of your Audi S4 (they are in most cases designated, and those on top must modify the verticality and the one on the side manages 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 component of the beam which should be a little to the right of the vertical line marked 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 down below.
  • Once finished, verify that the headlights setting of your Audi S4 is logical, do not hesitate to verify it after you have driven it, sometimes it may move.
