The headlights can be adjusted with Allen keys with the hood open. The adjusting screws have different meanings depending on the manufacturer:
On the outside (1) of the vehicle with Bosch product: lateral adjustment; for Valeo products: height adjustments.
On the inside (2) of the vehicle with the Bosch product: height adjustment; for Valeo products: lateral adjustment
The headlight adjustment cannot change itself. But if the reflector or even the entire headlight has been replaced, then you need to check the headlight beam installation.
Adjustment is also required if the front part of the car was damaged in an accident or after installing new shock absorber parts. Installation is carried out as follows:
1. First, set the light range adjustment to "0".
2. If only one headlight was damaged or replaced, then at first it is enough to park 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 beam of the headlight that remained unchanged.
3. If the headlights were adjusted using a device in the workshop, then 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 marks. With the help of such markings, you can always, when necessary, check the adjustment of the headlights on the Audi yourself.
5. The most accurate method of adjusting headlights is, as always, adjustment using an adjustment device, such as those available, for example, at petrol stations, in Bosch service centres and in workshops.
6. The high beam and fog light adjustment in the integrated headlight is set automatically if the low beam is adjusted correctly.
Where are the set screws located?
- The headlight mounting screws are accessible with the hood open from above through holes in the metal of the lock.
- A hex key is used to turn the set screw.
- When adjusting the headlight beam, the height setting is adjusted first. Only then should the lateral adjustment be made.
