Headlight adjusting not working. non xenon

[beemer]

Hi, I've been trawling through lots of post, but can't seem to find my problem, so wondered if any of you wonderful people might know?

I have the halogen headlights, so no self leveling stuff, however the interior adjuster makes no difference to the lights level.
When the lights are on you can hear/see the lights trying to adjust.
This is happening on both lights simultaneously making me think it's not a broken unit and maybe something else.

Has anyone had anything similar, or point me to anothrr thread?

Thanks.

Are they at their lowest setting? i.e. do they rise up when started?

 

[beemer]

Yes, they are at their lowest and they don't rise or do the up down motion on startup. They just click constantly like they're trying to move. Makes no difference where the interior adjuster wheel is moved.

Halogen dont self level - only the Xenons. Change in the level is caused by the interior adjustment to vary the height with a change in load (I think) :?

 

[Scooba_Steve]

They don't self level but they do park in the lowest position then cycle to setting. If it sounds like it is trying to do that then the LCM must be sending commands correctly. If I'm honest I wouldn't know where to start trying to fault find aside from check for fault codes then whip the lights out to see if there was anything disconnected :|

Hooked it up to laptop and no codes come up, so guess next thing is to just take them off and have a good old route about.
As has been said, non Xenons don't self level, you have to use the adjuster on the lcm, but they do physical move up and down on start up, and when adjusting.

Obviously not a common problem, so will see what I can find this weekend.

have you checked the settings of the manual adjustment screws on the headlights ? You may have them set so the internal adjustment screw cannot alter the level?

My drivers side headlight beam has been stuck down for a while now. Haven't got a clue what the problem is but the passenger side one adjusts perfectly fine.

It got stuck down last year and magically fixed itself after a few weeks (i could hear the clicking like you can). Now it's completely dead and no amount of wheel turning inside the car will fix it

Well I found out why it isn't working. A torx screw has come loose and the whole inner is basically free to move all over the place :lol:

Luckily I was able to tighten it up and all is now functioning as it should! Result.

Bloody bmw's!

Thanks Ben G, will definitely give that a go, sounds a likely culprit! Didn't get a chance to whip the bumper off today, so will have a go tomorrow.

Think I have the same problem with my xenons (pre-facelift) which seem way too high all of a sudden and are getting me flashed. Will try and listen for the clicking and check for travel on manual adjustment. Otherwise, when added to the ginger indicators it's another tick in the box for going aftermarket headlights.

Well I'm little stumped..

Took the lamps out, all move fine on the adjusters, tried another known good Iight and it does the same thing with the clicking solonoid, so now think it is a problem with the lcm!

Have just unplugged the electric adjustment and adjusted manually on the light itself for now until I figure out what could be wrong. :thumbsdown:

Hi [ref]beemer[/ref], I have the same issue, did you fix yours?

Hi,e85n52b25, welcome to the forum. Sorry can’t help you with your lights but someone no doubt will

Turns out it was a faulty contact in the 4 pin connector of one of the adjuster motors.
Changing the motor fixed it for a day, then the fault came back. Jiggling the wires on the connector fixes it for a while.
