How to adjust the headlight height on A4L?
1 Answers
A4L headlights can be mechanically adjusted for height, which involves adjusting the proportion relative to the vehicle body level. Under stationary conditions, the headlights can be relatively adjusted using the small hexagonal wrench located on the left front fuse box. Afterward, the level sensor will reference this height value for further adjustments. The left headlight's cutoff line is set lower than the right headlight's for safety reasons. Generally, the factory settings are optimal, and manual adjustments should be avoided. More details are as follows: 1. Car headlights, also known as front headlights or LED daytime running lights, are not only crucial for a car owner's appearance but also essential for safe driving at night or in poor weather conditions. The use and maintenance of car lights should not be overlooked. 2. Only the 1.8T version of the Audi A4L comes with a headlight height adjustment knob. The 2.0T and higher configurations do not have this knob, as the headlights automatically scan and adjust their height when turned on. This is because the high-end xenon headlights feature a bi-xenon projector system that automatically adjusts the position of the internal shutter to control the light height, eliminating the need for manual adjustments. The lower-end models use separate halogen lights for high and low beams, allowing for manual height adjustments.
