Hi,
Hope this is right section for this rather than electrical section :)
I have auto levelling xenon headlights and I don't know if its me being paranoid, but I seem to get flashed a lot when on dipped beam. :(
I used to have Low Beam/Fld Vision warning but cured that with new sensor on rear.
Is it possible to manually lower the lights at all, as I have to admit, the beams do seem way higher than any other car I own/have owned and seem to light up better than other cars do on full beam. I ask this, as when I bought the car it had the fault light on, which I believe lowers the lights to their lowest position. Could it possibly be, that the lights were raised manually by the previous owner (for MOT purposes), from the lowest position, and now that the fault is corrected, the lights cannot drop to the lowest point. :(
I hope this makes sense ;) and there is a cure, cuz I am really worried about night driving now :'(

It might be the link on the suspension that has come adrift, Like a ball and socket joint.
Have a look as that controls the level. I believe that the aim is factory set and can be adjusted by Tech2 .
If the linkage is intact then it could be the control rods have broken inside the actual lights. There is a sticky in one section for an aluminium replacement. Please be aware that the xenons have a very high voltage present if you intend prodding around!
A final thought is that there are levers on the back of the lights (remove the rubber cup) and these adjust the beam for contintal driving. They may be in the wrong position. On a UK car for UK driving they should be as follows. Driver side down Passenger side Up
Someone more knowledgeable will be along shortly!

Somewhere .. but I can't find it now ... MarkDTM put up a "noddy's guide" to adjusting headlights ... needs a flat surface, a wall, some chalk and some dark, and a couple of screwdrivers.
Either that or pop into an MOT station and ask how much to check/set the lights ??

there is a manual adjuster, it's what breaks and the ally adjusters have been made to replace.
One of the adjusters does left/right t'other does up/down.

Thanks for responses fellas :y
So it does seem that self levellers can be manually altered then.
I'll have a butchers tomorrow at joints etc, and then if no luck, I am over Brackley on Monday, so will see if TB can Tech 2 it. :y

They need a datum point to auto adjust about, the manual adjuster does this. It's only the same as a headlight with a 0 1 2 3 electrical level positioner, they still have a datum point they adjust to.

Hi fellas....
I am still having trouble with headlights...definately still high as people are still flashing me. >:(
Andy's pic shows clearly the adjusters, and I notice there are knurled nylon pieces on the rear of the spindles. When I turn the hex allen key, the nylon rear moves too. Is this right ???? Or should I try to hold the nylon end with pliers, or are they knackered. :'(
I am thinking that adjuster motors ?? may not be well, as I don't hear any noise from them when I put lights on, or indeed, see the lights move.
On top of all this, I came home from Brackley tonight, got flashed a dozen times....then got a flippin' puncture and had to get RAC out :'(
Mrs T getting a bit stroppy now about things going wrong....and I don't want to sell it :y

The adjusters go inside the headlight assembly, so I'm not to sure which nylon bits you mean.
As you turn the adjusters, you should be able to see the bottom of the reflector move relative to the fixed bit around the outer edge.

The nylon pieces I refer to Andy, are on the other end of the spindles you have highlighted in your piccy, mate :y

The nylon gears should turn with the rod AFAIK, they then move the nylon 'sliders' that are inside the headlight casing (and invisible) - these snap and there are billet alloy versions available in the OOF shop to replace them.

from what I remember there are nylon bevel gears on the end which then turn another rod inside the light somewhere.
Isn't there a picture of inside a headlight re the ally adjusters? :-/ :-/ :-/

There are.. damned if I can find them now, though!

click on the head light adjuster fitting guide (MS doc) towards the bottom. The nylon gears should turn with the rods that you're turning from the front of the light. :y

Thanks Andy and others....its really much appreciated :y

Just to add to this, I find the Allen key adjuster on the front of the light sometimes does not engage the nylon wheel at the back as said, you can help it turn by placing a spare hand at the back of the light and turn the nylon gear and allen key adjuster at the same time, in fact as they are so fragile I would suggest that as standard procedure tbh.
These will need several turns to achieve very little adjustment, so suggest park the car close to a garage door or similar and watch the beam for movement, if it moves sideways you have the wrong adjuster. Once you have sussed which adjuster and which way to turn it(if the adjuster is not broken of course)....
Drive the car as close as possible to a garage door or wall, lights on, mark the position of both beems, reverse up 6feet or so and adjust the beam so the new position sits about an inch below the previous mark.
Note, there is a marking somewhere on the headlight that gives the ratio of dip per distance of beam. By working out this ratio, the percentage of drop from the mark on the door can be calculated from the distance the car is reversed up. But I never bothered with that ;D
Reverse up 6feet and adjust to give an inch drop, then drive the car at night, adjust from there.
Do try to get it right though, too high beam is very annoying. :y
-
Good reply, buddy. :y
I fully appreciate how annoying it is to be dazzled....I cringe every time a car comes towards me, waiting for the dreaded flas, flash :( :(. Not using the car at night now, until I sort it. :y
I have been trolling through the forum for any info and your reply, mate condenses all I have found. Been twisting the adjusters, but have been poncing about with quarter turns ;D ;D instead as you and others suggest ...mega turns.
As a last elimination...if the headlight motors were not working, would that show up the Low Beam/Fld Vision fault light. I have not had that light since I renewed the rear sensor. ;)
