How to Fix Audi Adaptive Headlight Malfunction?
2 Answers
Audi adaptive headlight malfunction can be resolved by: driving the vehicle to a repair facility, using professional diagnostic equipment to read the fault codes stored in the system to identify the cause of the malfunction, and then performing measurements and comparisons of the data to locate the issue and carry out the necessary repairs. Additional information: Working characteristics of adaptive headlights: 1. Adaptive headlights are automatic headlight range adjustment devices, also known as automatic headlight leveling systems. They use body position sensors located above the shock absorbers to detect the vehicle's speed and pitch angle (upward or downward tilt), automatically adjusting the headlight beam height accordingly. 2. While ensuring adequate illumination, they prevent glare for oncoming vehicles.
Last time I drove an Audi A6L, I also encountered an adaptive headlight malfunction, and a fault warning popped up on the dashboard. I first did a few things myself: checked if there was any dirt on the camera above the windshield and wiped it clean with a soft cloth; then restarted the vehicle system to see if it helped. When the problem wasn’t resolved, I went to the 4S dealership for a computer diagnostic test, which revealed that the headlight control module needed a software update. The technician mentioned that such issues are mostly caused by software bugs or radar obstructions, advising to keep the camera clean and avoid using high-pressure water jets directly on the headlights during car washes. If the module’s hardware were damaged, replacing it could cost around seven to eight thousand yuan, but fortunately, mine was still under warranty. These smart headlights are quite delicate—driving fast on bumpy roads can also easily trigger malfunctions.
