BMW’s automated headlights are a great feature that can enhance your driving experience, but when they malfunction, it can be frustrating and even dangerous. There are several reasons why your BMW’s automated headlights may not be working correctly. In this article, we will discuss the most common causes of automated headlight malfunction in BMWs.
1. Sensor Malfunction
The sensor is the component of the automated headlight system that detects changes in the light level outside the vehicle and signals the headlights to turn on or off accordingly. If the sensor is malfunctioning, your headlights may turn on or off at the wrong times, or not turn on at all.
One common reason for sensor malfunction is a dirty or damaged sensor. Dirt or debris can accumulate on the sensor and prevent it from functioning correctly, while the damage can cause the sensor to fail altogether. In some cases, the sensor may need to be replaced to fix the issue.
2. Electrical Problems
Another common cause of automated headlight malfunction in BMWs is electrical problems. The automated headlight system relies on a complex network of wires & connectors to function properly. If any of these components become damaged or disconnected, it can cause the headlights to malfunction.
For example, a loose or damaged wire could prevent the sensor from sending the correct signal to the headlights, causing them to turn on or off at the wrong times. Additionally, a blown fuse or a faulty relay could prevent the headlights from functioning altogether.
3. Bulb Issues
If the bulbs in your BMW’s automated headlights are burned out or damaged, it can cause the headlights to malfunction. In some cases, a single bulb may burn out, causing one headlight to function correctly while the other does not. In other cases, both bulbs may burn out at the same time, causing the headlights to stop functioning altogether. If you suspect that your headlights may be experiencing bulb issues, you should inspect the bulbs and replace any that are burned out or damaged.
4. Control Module Failure
The control module is the component of the automated headlight system that manages the signals sent between the sensor and the headlights. If the control module fails, it can cause the headlights to malfunction. Symptoms of control module failure may include the headlights turning on or off at the wrong times, or not turning on at all. In some cases, the control module may need to be replaced to fix the issue.
5. Faulty Headlight Motor
In some BMWs, the automated headlight system uses a motor to control the position of the headlights. If the motor becomes faulty, it can cause the headlights to malfunction. Symptoms of a faulty headlight motor may include the headlights turning on or off at the wrong times, or not turning on at all. In some cases, the headlight motor may need to be replaced to fix the issue.
