Adaptive headlight system malfunction in your BMW X5 can put your road in jeopardy. Therefore, if you’re suspecting that your AHS is going out, be sure to have it tested by a certified professional as early as possible.

1. How To Know If Your
Are Malfunctioning?

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

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

4. 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

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

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

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

11. Stepper motors are
responsible for
adjusting headlights
when you corner.

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

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

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

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

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

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

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

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

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

27. AHS is an important
safety feature.

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