Headlight Trouble

[chrissoto312]

Hey guys,

I"m needing some help here.

First off, when my auto-sensing light indicator goes off, as soon as i turn my steering wheel right and then return back straight, the green indicator light begins flashing. Right off I can see that my passenger headlight isn't aiming straight again, it's off to the right. So, it's obvious I need a new headlight(s).
On startup, the auto level still works, but it won't go side-to-side basically.

So, can anyone tell me where I can get a new headlight assembly? Or what it is that I need to do?

I don't know much about the facelift adaptive headlights but before you go for a new headlight which is probably very expensive I'm assuming maybe to check the operation of the leveling motor, or maybe the sensor on the passenger side under the car to see if its busted first?

if the light on the switch (S8) is blinking, it might indicate the problem with the LWR unit not working properly and not controlling the headlight properly, or the headlight that is not working properly and reporting trouble back to the switch via the LWR module... So, the problem could be inside the headlight or in the control module... swapping part to test the either theory can be expensive adventure.

Yes, that's what I'm trying to avoid. I find all these headlights online, but none of them are "Adaptive Headlight" compatible

sound like bad auto levling sensor.

Thanks, do you know where I can get one of those?

check out your headlight diagram on RealOEM and get the part number and order from your favorite online vendor or parts dept of dealership!

chris,

the adaptive lights are working independent from each other, they go up and down and left and right individually, like eyes on a chameleon... when the engine starts, the car systems do a check of the functions, for the headlights it means that they go up/down, and left/right. you said, that they do go up/down, but do they go left/right? also, while the engine is running and you are statioanry, when you turn the steering wheel to the right, does the light turn? both? only one? none? when you turn the steering to the left, the lights will center but will not turn to the left, so, you need to turn the wheel to the right to see if the lights move.

lets try to troubleshoot the problem before throwing money into it...

Yes, that's what I meant. I start up. They go auto adjust, up and down and the auto on headlight indicator is a solid green.
I put it in gear, start moving forward and turn right to leave my place. Indicator is still solid.
As soon as I rotate my steering wheel to straighten out, the indicator starts blinking.
Now, in the past, when I'm still and my headlights are facing a solid object, I could turn my steering wheel and the headlights would move right to left. Now, the passenger light doesn't move at all and it almost seems it's misaligned to the right a bit.

Man, I'm really stumped as to what it could be. The guy on bavauto.com said one headlight was about $1400.00

i will be home in a few hours, and i can check the WDS blueprints. your issue can be mechanical, stripped teeth on motor gear, or electronic. if you have time, stand by and we will try to narrow problem down.once more, since i am retarded, and need info repeated several times, - the right "eye" does not move left/right. what about the left "eye"? can you check to see if left "eye moves or makes an attempt to move left/right?
