Maintenance: Adjustments Audi A6 C5 facelift

Setting low beam alignment of driver's side headlight

1. Move Beamsetter into position in front of the vehicle so it is aligned with the vehicle and Beamsetter box is 30 to 70cm (12 to 28 in.) from the driver's side headlight.
2. Switch headlights ON in low beam position.
3. Align Beamsetter box so it is centered on the headlight (align vertically then horizontally). NOTE: Use the arrows on the Beamsetter box as a guide. You may want to use a straight edge or tape measure, because alignment must be within 3cm (1.2 in.) of the center of the headlight.
4. Without moving the Beamsetter, slide Broad-band sight toward center of vehicle (Broad-band sight can also be moved up and down for a better position).
5. Loosening hand-wheel that locks column in place.
6. Sighting down through the slit in the Broad-band sight and rotating Beamsetter box and column until two similar points on vehicle are aligned.

Note. Try using corners of the headlight housings or two screws that are the same height and as far apart as possible on the vehicle.

1. Carefully tighten hand wheel without changing Beamsetter position.
2. Set Inclination to 1.0 %.
3. Set Beamsetter "Scaled wheel" to the proper low beam inclination %.
4. Adjust height (vertical) alignment first. Turn headlight height adjuster screw to align the upper edge of the flat portion of the beam with the center horizontal line of the grid on the Beamsetter pattern screen.

Note. VOL is the correct beam pattern for both right and left headlights.

Scheme 3

1. Adjust lateral (horizontal) alignment of driver's side headlight so that the peak (highest point) of the headlight beam pattern aligns with the right edge of the target box of the grid on the pattern screen (it should match the VOL pattern shown on the Beamsetter box).

Note. If the height alignment changed, readjust.

Checking driver's side headlight high beam alignment

1. Switch headlights ON in high beam position.
2. Realign Beamsetter box with the high beam headlight if necessary.
3. Set Beamsetter "Scaled wheel" to 0%.
4. Cover low beam lamp (use hand or small piece of cardboard) and make sure the "hot spot" of high beam pattern is centered on the square target box of the pattern screen.

Note. High beam pattern is built into the reflector design and cannot be adjusted separately.

If high beam pattern is way out of adjustment

1. Inspect for reflector damage.
2. Replace reflector if needed.

Note. Always align headlight in the low beam position.

Passenger's side headlight, alignment

1. Move Beamsetter to the passenger side of the vehicle and follow the same procedures to align the Beamsetter box to the headlamp.
2. Align headlight low beam, check high beam and align fog lamp. NOTE: Make sure to reset the Beamsetter "Scaled wheel" to the proper setting each time you change from low beam to high beam or to fog lamp.
3. Make sure that headlights and vehicle body are clean and free of fingerprints.
