How to Fix Volkswagen Headlight AFS Malfunction?

[VanOscar]

For Volkswagen headlight AFS malfunction, it is necessary to check whether the bulb and the sensors under the chassis have been flooded or impacted, and to inspect if the headlight control unit has been flooded. If everything appears normal, you can visit a 4S shop to diagnose and resolve the issue by checking the fault codes. Below is relevant information: 1. Adaptive Front-lighting System (AFS): The AFS is a feature where, when the vehicle's headlights are turned on during night driving, the headlights use sensors—typically a camera located on the inner side of the windshield—to detect the presence of oncoming or same-direction vehicles and pedestrians. This allows the driver to focus more on driving without frequently switching between high and low beams. 2. Principle: The AFS utilizes a camera positioned near the rearview mirror to detect vehicles ahead, with a detection range of up to 400 meters. If an oncoming vehicle is detected, the system selectively blocks the high beam's light range to avoid shining directly on the vehicle. This ensures the driver maintains clear visibility without affecting the oncoming vehicle. When the system detects no vehicles ahead, it automatically switches back to high beam.
