Bi-Xenon auto leveling feature has a mind of it's own (Where are the sensors)
If so can someone please point out their exact location front and back? Mine can't make up it's mind what it wants to do. If it's true that this is the location the dealer may be responsible because of a recent repair. Post 17...http://www.xoutpost.com/bmw-sav-foru...hids-same.html Quote:

Front Axle Levels Sensors
For the front sensor, it should be connected to the RHS control arm and located at the non-moving end with its position sensor arm able to move freely. This end is attached to the swing arm I think. If you have air suspension all round, it's all part of the same sensor system, but with the additional functionality built in. Rear Axle Level Sensors Hall effect sensors are mounted on the left and right sides of the rear suspension for ride height detection. They are pivoted by a coupling rod through the rear axle swing arms. The hall sensors produce a varying voltage input to the control module as the suspension height changes. If the vehicle is equipped with Xenon headlights the right side sensor contains an additional sensor for the automatic headlight level adjustment system. In both cases look for a block (the sensor) and it's associated levers on the RHS control arms at both ends of the vehicle. You may have sensors in all corners if you have full air suspension, but only the two on the RHS are used for the light levelling system. I do have a copy of a BMW TI (in pdf) of how to install the Xenon HIDs as a retrofit, but can't upload it as it's too big (1.2MB). It has all the diagrams of where the sensors are and the wiring etc. Only for use on LHD cars!!

welcome to the board. what is your problem? Lights going up and down? Most likely your front sensor arm is in the wrong position. Jack the car a little, get underneath, see what direction it's going, jack it up to full extension, lower the car and make sure the arm goes the other way.
anyway, here are the parts and illustrations. RealOEM.com * BMW E53 X5 3.0i HEADLIGHT VERTICAL AIM CONTROL SENSOR

Thank you Reckless. Really appreciate your answer.
I recently replaced my front axle boots (both left and right) from a shop (not dealer, but a bimmer specialty shop). After the CV boots replacement, I noticed both my head lights go up and down on the highway randomly. After checking these posts, I suspect this is related to that sensor and went back to the shop. The shop however told me that there is no way they could installed it wrong since there is only one way to install it.

Ok, and since we are talking about the leveling headlights... I have the DEPO brand headlights. My self level never worked on my DEPOs but did on my stockers. This spade connector is on the self leveling motor, in the headlight housing. There was a (black I think) wire connected to here on the stockers, but the wire was coming from the stock head light. My after market ones did not have this wire. So can someone tell me if this should have 12v or should it be grounded?
