How To Know If Your

Are Malfunctioning?


Adaptive headlight system (AHS) is an advanced driver assistance system.


Its job is to regulate the headlights so that you can get better visibility on dark curved roads.


To enhance your visibility it employs the following parts; • An electric control module • Wheel speed sensors • A steering angle input sensor • Stepper motors • A yaw motion sensor


They act jointly to make the headlights adaptable to different driving conditions.




Of all the reasons your AHS may go out, a faulty control module tops the list.


Until you replace the control unit, your AHS will not work.



Stepper motors are responsible for adjusting headlights when you corner.


Defective stepper motors can put your vehicle’s AHS in jeopardy.



Another common cause of AHS failure is condensation due to defective seals.


If you’re noticing signs of condensation in your headlights, get them tested.



Several signs can indicate issues with your BMW X5 AHS. Some of them are as follows.



A common finding in a BMW with a faulty AHS is the "adaptive warning light".


Call a technician to diagnose and fix the reason behind the appearance of this light.



Another sign that your AHS is failing is the appearance of the "Adaptive headlight malfunction" message.



If your headlights are not adjusting themselves when you corner, chances are your AHS has gone bad.


Have your BMW X5 inspected by a qualified mechanic to determine the cause.



AHS is an important safety feature.


Therefore, you need to ensure that your BMW X5 AHS is in excellent condition.
