The headlights on a BMW are often called adaptive headlights. This is because they can move the projection of light to the right or left based on how you drive. This provides more clarity to the driver when they turn or go around corners. When they work properly, they can limit blind spots and reduce accidents on the road.

Some models of the BMW will take these headlights to the next level with automated LED headlights. These lights have the ability to change the brightness when a car comes closer. A light camera inside the headlights can detect the lights from another vehicle. With all of these sensors and electronic parts inside a simple headlight, it is easy to see how something can go wrong with the headlights.

Adaptive Headlights Failure

Car owners may notice a few different things that cause their adaptive headlights to fail. The BMW has many different components that come together to provide one of the best cars on the market. Since all of these parts work with one another, if something stops working, it may affect the others. Some of the causes of automated headlight failure in a BMW includes problems with the features below.

Adaptive Headlight Module

This module is found right under the headlight housing. In the BMW, it may be known as the Stepper Motor Controller or SMC. Since this is a control module, if it gets wet, it may stop working. The car owner needs to be careful about what kinds of liquids get near the module. Dropping your coffee on it or even heavy rain and flooding can get into the module and cause the adaptive headlight to malfunction.

When water does get into the adaptive headlight module, an error message will display on the BMW dashboard. As soon as this error message shows up, take your BMW into a certified mechanic to get the adaptive headlights fixed.

Headlight Seal

The access door around the headlights in a BMW should have a seal in place. The design of this seal is to prevent water from entering that area. BMW owners should check that seal and make sure it is secure if they ever open that access door to clean or replace a bulb. Without the seal properly in place, it is easy for water and moisture to get into the electrical components and cause trouble. Check that the seal is in place if you ever open the access door.

Stepper Motor

The stepper motor is important to your car. It is responsible for turning the beam projector any time you turn a corner. You can find this inside the headlight and the power comes from the control module right under the headlight. Over time, the motor for this can burn out.
