5 Parts to Check If Your BMW X5 E70 Adaptive Headlights Malfunction
The BMW X5 E70 is one of the most widely owned SUVs due to its performance and advanced features owing its origin to 2006 when it replaced the BMW X5 E53. Packed with astounding features, the BMW X5 E70 is fun to drive until you start encountering adaptive headlight issues in your high-end car.
Of course, like all luxury cars, the BMW X5 is also prone to certain issues especially its adaptive headlights that can put you in a lot of trouble. Here in this article, we will discuss the crucial 5 parts of your BMW X5 E70 that you must definitely inspect when the adaptive headlights start acting up.
Adaptive Headlight Control Module
One of the first things that you need to inspect whenever the adaptive headlights start malfunctioning in your BMW X5 is the adaptive headlight control module. The Adaptive Headlight Control Module (AHCM) is the most vital component in your adaptive headlight system and it controls the working of the adaptive headlights.
Whenever there is an issue with the adaptive headlight in your luxury car then you mustn’t delay in taking remedial measures because it directly affects the safety of the occupants of your car. The AHCM collects data from the sensors in your BMW which is used to calculate the perfect position for the headlights of your BMW that would make it suitable for you to see the road ahead.
The data received from the steering angle sensor and the leveling sensor are crucial for AHCM to reposition the headlight actuators so that the beam doesn’t go astray. However, if the AHCM is itself faulty then your adaptive headlights are of no use because they won’t be able to adjust themselves as you are driving.
That is why it is crucial to inspect the Adaptive Headlight Control Module to ensure it is not the root cause behind the malfunctioning adaptive headlights in your BMW X5 E70.
Steeper Motors
Most BMW owners are not aware of the number of components working in unison to make their adaptive headlights functional. The steeper motor is one such least-known part of your adaptive headlight system that assist in the physical movement of your headlight.
The steeper motor assists the adaptive headlights to turn as per the driving requirements, road conditions, and speed of the vehicle. Now, if the steeper motor starts encountering issues with its functioning, then it won’t be able to carry out its functions in an efficient manner.
If the steeper motor of your BMW is at fault, then you are going to hear unusual noises and an inspection of the wires and connections leading to your steeper motor need to be inspected along with the diagnosis of the error codes of your car which will confirm whether the fault lies with the system or not.
Upon inspection, if you find that the steeper motor is malfunctioning then replacing the steeper motor is the only way out to restore the functioning of the adaptive headlights.
Wiring Harness
The adaptive headlight components and your car’s electrical systems are connected through the headlight wiring harness which transmits signals and power between the components. Most of the time it is seen that damaged wiring plays spoilsport in the efficient functioning of the wiring harness in BMW X5 E70.
At times, when there is a problem with the wiring harness of your adaptive headlights then you are going to face a host of issues with your lights including flickering headlights and the headlights won’t be moving as expected. Besides that, some BMW drivers also report facing complete headlight failure in their cars.
Headlight Level Sensors
There are a host of sensors used in your high-end car and the headlight level sensors monitor the pitch of the car to adjust the headlight’s vertical position so that drivers coming from the opposite side aren’t dazzled. Malfunctioning of the headlight level sensors can affect the efficient functioning of the adaptive headlights in your BMW.
Well, diagnosing a faulty sensor in your car is a complicated task and you must leave it to the professionals who will use advanced tools and equipment to detect the faulty sensor in your luxury car.
Xenon or LED Bulbs
At times, the type of bulb used in your adaptive headlights whether it is xenon or LED can go a long way in determining the longevity of the adaptive headlights. If the bulb used in your headlights have gone bad then it can lead to reduced intensity of light or complete adaptive headlight failure.
You can check the bulbs for any wear and tear and if they are damaged then replacing them with new ones is going to restore the functioning of the headlights.
Finally
