The headlight setting can be adjusted with Allen keys with the hood open. The set screws, depending on the product, have a different meaning:
On the outside (1) vehicle with Bosch product: lateral adjustment; with Valeo product: height adjustment.
On the inside (2) vehicle with a Bosch product: height adjustment; with Valeo product: lateral adjustment
Headlight adjustment cannot change itself. But if the reflector or even the entire headlight was replaced, then you need to check the installation of the headlight beam.
Alignment is also necessary if the front of the car was damaged in an accident or after installing new parts of the shock absorber units. Installation is carried out as follows:
1. First, set the beam range control to «0».
2. If only one headlight was damaged or replaced, then at first it is enough to put the car in front of a light wall, turn on the light and then adjust the height of the light beam of the new headlight to the height of the headlight beam that has not changed.
3. If the headlights were adjusted using a tool in the workshop, you can, for example, mark the height of the light points on the garage wall.
4. The distance at which the Audi stands from the wall is also important. Put labels. With this marking, you can always, when necessary, check the headlight adjustment on your Audi yourself.
5. The most accurate way to adjust the headlights is, as always, the alignment with an adjustment device, such as those found, for example, at petrol stations, Bosch services and workshops.
6. Adjustment of high beam headlights and fog lamps in a built-in headlight is set automatically if the low beam is correctly adjusted.
Where are the set screws located?
- The headlamp set screws are accessible from above through holes in the metal of the lock when the hood is open.
- A socket wrench is used to turn the set screw.
- When adjusting the headlight beam, the height setting is first corrected. Only then does the lateral adjustment follow.
