How to Adjust the Height of Audi A6 Low Beam Headlights?
4 Answers
Car headlights can be adjusted for brightness according to numerical indicators, allowing free rotation to modify the height and range of the headlights. It is recommended to inspect them every 50,000 kilometers or approximately every 2 years. If the headlight brightness is insufficient, replace the bulbs promptly, ensuring both sides are changed simultaneously to maintain uniform brightness.
I've adjusted the low beam headlights of my Audi A6 several times myself, and the steps are quite simple. First, locate the light control knob on the left side of the steering wheel inside the car. Audis come with electric adjustment function, so you can raise or lower the beam by rotating the knob marked with numbers 0-5. Remember to operate on a level surface facing a wall, with the front of the car about 3 meters away from the wall. After turning on the low beams, adjust until the cutoff line is at the height of the tire center, which is just right. If the electric adjustment isn't enough to raise the beam to the desired height, you'll need to open the engine hood. There's a white plastic screw hole at the back of the headlight assembly; use a hex key to turn it slowly, adjusting a quarter turn at a time, then get out of the car to check the effect. Setting it too high can dazzle oncoming drivers, which is dangerous, so it's advisable to take a test drive at night after adjustment to confirm the road illumination effect.
As a long-time Audi owner, I recommend prioritizing the use of the interior knob for headlight height adjustment. The roller wheel in the light control area on the left side of the driver's seat adjusts the beam height, with 1 being the lowest and 5 the highest. However, note that cargo in the vehicle can affect the automatic level calibration—loading heavy items in the trunk will cause the headlights to automatically tilt downward. If the lights still seem low after manual adjustment, the motor might be faulty. Audi headlights feature a precise active cornering system, and a damaged motor requires replacing the entire assembly at an authorized service center. During my own adjustments, I specifically tested that the low-beam cutoff line at 75 cm height provides optimal illumination at 30 meters. Beams set too high will also fail the annual inspection. If unsure, it's worth spending some money to consult a technician—safety should always come first.
Adjusting Audi A6 Low Beams? Don't rush—check the model year first. Older models use halogen bulbs; simply turn the adjustment screw behind the lamp base with a screwdriver. Post-2015 models feature LED headlights, requiring electric adjustment via the dashboard wheel. Locate the up/down arrow knob on the lower-left dashboard near the steering wheel. After starting the car, rotate it left/right—the beam cutoff line will move accordingly. Always adjust when the car is cold; hot conditions slow motor response. The wall-marking method is most reliable: park 5 meters from a wall with low beams on—the beam's cutoff line should align with half-wheel height. Avoid over-adjusting; exceeding legal height risks traffic police fines.
