I'm looking to replace my headlights (hella xenon, auto level) with some used xenon hella units. Can I assume that if they are also xenon and post-facelift that they are going to be self leveling? If they are but the used headlights have some issue, can I retrofit the motors from my existing lights?
TIA.
Yes they all are, and yes you can.

Great, thanks!
I could be wrong, but I think the adjusters being broken on the used Hella's is much more likely than an issue with the auto level motor.
What is wrong with your current lights?
fyi if you are unaware in 2002 hella switched to a different type of adhesive that can not be opened with heat. There seems to be some confusion as to whether it was 7/2002 or 9/2002. If the lights were made after the cuttoff date and you want to remove the lens' is it possible, but it involves patience and you the original lens is destroyed in the process. Then you have to replace them with new lens (on the plus side you can use a butyl sealant to reseal the lights so if if you ever need to open them again you can more easily). Here is a thread on the process if you need it.

The issue with headlights is that I am vain and want the clear corners... and want to stick with what we know looks good and works!
Ive read the tutorials to swap your lenses only, but a) I don't think my lights are the ones you can bake open and b) even if they were, this is not the place for me to me an expensive mistake.

Hahaha I like that honest answer. Well the upside to buying this set is you will now have a spare set of lights so if you ever need to swap in new adjusters or want to upgrade to bi-xenon you can at be comfortable that you have a good set up backups. Or of course you could sell them to offset the cost of the ones you are buying.
I am sure you are aware, but just in case you are not I want to mention that these headlights are notorious for having broken adjusters due to the brittle material the used to make the original adjusters. So you may want to make sure the adjusters are not broken on the new lights or better yet if the owner changed them already (the replacement parts usually are made from a better material although it may depend on where you source them).
fyi once you remove your current lights it is easy to check the date stamp on the back to determine if they can be opened. This recent thread talks about the date and there is a pic in there of what the date code looks like.
I am not trying to convince you not to buy another set of lights, you know your diy abilities and comfort level better than we do. And you are willing to spend the money on another set of lights. But just so you know opening up the bakeable lights is pretty easy, even if it seems a little intimidating at first. Also you don't have to use an oven if you don't want to, a heat gun will also work (not a hair dryer but an actual heat gun). If you are really paranoid you can buy a heat gun that has a variable temperature control so you can figure out the lowest setting that will make the butyl pliable. I used a heat gun to open and reseal my lights and it worked great.

In Europe, ALL projectors (Xenon & Halogen) lights have self-leveling, by law.
In America, only Xenons have self-leveling. Halogens have a dummy actuator motor.
But, yes, halogen housings can be converted to xenons. I HAVE ALL THE PARTS NEEDED for this task.

Mach540's answer is correct if you are checking for broken adjusters which is the more common failure. Not really a huge issue, but depending on what you are trying to diagnose it may be helpful to know the auto leveling system and adjusters are two different things that work together on cars that have the auto level system.
The adjusters allow you to set the aim of the headlights. The auto level system makes minor adjustments based on vehicle load. Jim Cash's description is better:
The BMW leveling program does the following:
- a calibration run on each start up.
- Adjusts light height for changes in vehicle load as determined by the suspension sensors. This is normally checked every 30 seconds and minor adjustments done as required.
- "Immediately and constantly" adjusts the height of the lights during periods of acceleration or braking so as to prevent these movements from affecting the level of the lighting.
Note - the autoleveling does not correctly aim your headlights. You must first aim them manually according to specks and then the LWS system will keep them at the proper level for the above situations
The auto level system consists of a front sensor, a rear sensor, a LWS module, and the auto level motor on the back of the headlight. A failure of any of throw off the height adjustment of the lights. The LWS is connected to the LCM (all e39s have an LCM) so a failure of the LCM might also cause a height adjustment issue, but I am not sure. I am not sure if a failure of any of those components will cause an error light on the dash, but they might trigger a error code that you can read with an OBD scanner and/or something like NCS.

I've had problems with level sensors and got no warning lights. The faults did show up on a diagnostic scan.
Not to be objectionably picky/anal, but the auto-leveling module is an LWR. You won't find an LWS module.
And for scanning for fault codes you'll need a full function BMW scanner, e.g. BMW's INPA or DIS, or aftermarket PA Soft, etc. . A generic OBD scanner won't see the LCM or LWR.

I’ve replaced adjusters for 7/02+ units. It’s not easy. It can be done by stripping the back of the headlights of all gaskets and tapping out the celis assembly (3-spoke metal assembly) out of the way. Remove the old/crusty adjusters like usual. Use your fingers (index and middle) to feel you way in there Try to catch one of the holes of the adjusters onto the stud and turn the 10mm external boot to pull the adjuster in. Reinstall the celis assembly and straighten it out.

I've done all this with the housings apart, how in the hell do you do this by poking two fingers in there???????? How do you take the busted ball end out of the sockets??????? You must be one hell of a gynecologist....

With screwdrivers forceps and tweezers. You're quite right that fingers alone won't work.

This is a good thread for anyone wishing to replace the headlight lenses. It turns out that someone dug up and re-posted the original post on page 7 of this thread

You will need the leveling actuator.
