xenon lights self leveling - Page 3

The sensors are attached to the front and rear offside suspension arms and the 'chassis'. Later models only have a single unit at the front.
The front sensor access requires removal of the wheel arch liner.

There are photos of both units in Post 4 here: http://www.the75andztclub.co.uk/foru...ad.php?t=21583

Both leveller ams seen here have flipped and the rear arm has detached from the suspension.

Are these picture looking at the drivers or passengers arch..

Is there anyway of seeing this assembly without removing the wheel and wheel arch liner.?

It is the drivers side and with the wheel turned to maximum you probably can have a peek at the front one. No need to remove anything.
To correct it if bent the wrong way, you need to get access or have a very long arm. Taking the wheel off can then be handy.

Thanks Rob, will have look tomorrow if its dry.

The arms should be in an inverted V shape....this one is wrong

When the ECU detects a problem, it automatically drops the lights to the lowest position so as not to dazzle oncoming roads users. The MOT tester would fail it on headlamp alignment, not the fact the leveling system is not working

My two sensors, the white stuff is just spray grease. They both look normal, so I played around with the plugs and joints. Gave them a quick spray of grease and hey presto the levelling is back working again.

So much for our cars being phosphor dipped or whatever it is,,, why the heck do the suspension parts seem to take on rust so easily????
Don't see this on other cars of this age!!
Feel like scrubbing all the bits and re coating them in something really tough!

I had the same problem where the light would adjust and drop to the floor, so I checked the chassis adjusters and all is well.
Next I took the xenon apart and then checked the motor, it would work some of the time then it made a grinding sound and the adjuster then went fully out, (light pointing to floor), a gentle tap and it would work fine then the grinding sound and out it went again.
I have ordered a new motor from Germany with freepost for £22, the same item from a bmw dealer in the uk.....£117.54.

A link to the supplier might prove useful.
