Steering linked headlight

I've been looking around and I haven't read anything thing about them ?
My car has them but they won't turn left I was wondering if I had to change the whole headlight unit or just the motor that turns them ?

It doesn't turn left when you're stopped. Are you sure it doesn't turn left when driving? Malfunctions of the dynamic xenon feature tend to be indicated by the LED light blinking.

Need more details to answer better.
Also are you setting the LCM switch in the correct position?
You have adaptive xenon's?

Yeah its on the right position, Like if I'm driving slow and turn the steering wheel to the right a little I will see the movement of the light in that direction , When I do it to the left not as much . Is there a motor that moves the lights?

** just went for a drive when I turn right it reacts more then to the left , like its more sensitive to the movement when I turn right , so when I'm driving Down a straight road at like 60km and turn the wheel a little to the right the AX will move , but if I do it to the left just a little movement , it's only when I make a full left turn that they will fully engage on the left side .

So is there some type of actuator or little electric Motor that can go bad ? Or does it need a little grease ?

did the always did this ever since you've owned it? I would think that it wouldn't veer to the left as much, perhaps not wanting to endanger and blind oncoming traffic just because you were slightly swerving and was only trying to correct yourself. then again I would assume the lights also leveled themselves to avoid blinding on coming traffic. the lights moving during hard lefts would indicate to the lights that you were actually making a real turn around a corner or a bend. I don't know. I didn't even know these were available for our cars. cool.

That sounds fairly normal to me. The motor turns to a higher degree on the right side than the left side to prevent traffic from getting blinded.

Active lights do not turn when the car is stopped, they turn more to the right than the left as well.

Best way to verify what is going on find a sweeping right turn at night, then quickly turn wheel back to the left a small amount and you will see the lights move quickly.

Likely the lights are fine, the amount they turn is not overly obvious unless you know what to look for.

Not disagreeing, just adding perspective.
When I'm driving with my Bi-xenon's in the auto position and have the high beams on, here's what I experience. Driving straight ahead at about 20mph when I pull my steering from side to side, I notice a real sweeping of my lights from side to side. And the sweep to the left and right appears to be very even.

I would assume that in high beam mode, the car will trust the user isn't having them on to be an a$$hole and blinding people asking it to do what it's intended purpose was, to give driver max visibility with no sacrifice or care to blinding. Again, i don't own these type of lights. I'm just thinking like a computer and processing logical reasoning why it was designed that way. End thread.

Do not think I have tired with high beams on, they may react differently??

You will see a large left hand swing when pulling back from a right hand swing, but not from center in my car.

They may also move a bit more at higher speeds?? I have not tried to make radical movements over about 20-25 MPH.

Practically speaking, the only time I have really thought them useful and a practical thing is in the Hollywood hills where you have to wind up many curves to get to my friend's house late at night. Other than that for me, I'd think of them as a gimmick.
