Hey Gang,

I have now performed my first E39 Xenon with Angel Eyes, Headlight adjuster
extraction and replacement. Just as a refresher, these are the adjusters
that are not available from BMW but Jeff Caplan over at Odometer Gears Ltd.
created. The Adjusters from Jeff are very similar to the originals but
according to him they are made from better materials and should last longer.

The replacement procedure is not difficult but time consuming since you have
to take your time prying the plastic lens from the backplate assembly. I
started by first removing the headlight from the car(duh!). The rest of the
directions I will number.

1. After removing place on a clean soft work surface, like a towel. Have a
place to keep all of your parts that is off from your general work area
since you will be doing a lot of turning and pivoting of the light assembly.
2. Remove the remaining bulb sockets from the housing.
3. Remove the Xenon Tranformer.
4. Remove the two tiny torx screw in the back of the assembly behind the
lense where it sweeps into the fender area when mounted in the car. These
two are easy to forget but it is critical to get these out.
NOTE: The next process is time consuming and requires patience so if you
are a fumble fingers or a spaz find someone else in the shop to do this.
You now ready to seperate the lens from the housing. It is glued in with a
non-hardening produst like gorilla snot.
5. I start this process with a large flathead screwdriver. You will need
to seperate the lens from the assembly enough to get the clips over the
keeper. To do this work your screwdriver down between the clear plastic
lens and the black housing and firmly twist and hold. You will note that it
will start to move and return back to its original place. You will continue
doing this around the outer edge until you have successfully gotten at least
a few clips beyond their keepers. You won't get all the first time.
OF NOTE: I have tried heat from a heat gun and although it works well on
assembly I haven't really noticed it helping on dissasembly.
6. Once you have achieved some space in the contact point between front and
rear portions you will now be able to get to flat head screwdrivers
sandwiched to gether into the gap and use those prying against each other.
Once again the rubber contact glue will want to pull it back together as you
release but eventually it lets will stretch and hold. Continue this
process around the outer edge in even increments until you have seperated
enough to see the gorilla snot pulling.
7. Once you have seperated the front from the back enough to get a
screwdriver or flat bar between them, you will see the gorilla snot, not
wanted to let go. At this point I use a razor blade to slit the bond and
continue that process all of the way around.
8. By the time you get this far you will have figured out the general
routine. Once you get both halfs apart will now be able to see inside the
assembly. If you succesfully seperated the two without pulling the inner
"Angel eyes" with the lens then you now have to remove it from the backing
plate assembly. It has 4-6 contact points that hold it in place. Pull
gently and evenly at all of the points until it lets go.
9. Remove the 3 torx holding the self leveling adjuster and from the front
side you will need to reach in with a long screw driver and push the ball
contact in the direction of the opening in the keeper so that it can be
removed and put it asside.
10. If both adjusters were broken you will now be able to pull the
reflector assembly out, there will be a ground wire still attached,
disconnect that.
11. If one is still intact then turn the adjusment screw on the opposite
side untill the adjuster releases.
12. After you have the reflector out of the way remove all of the debris
from the housing.
13. After dabbing a bit of Wurth Glide or a similar product on the hole to
be threaded in the new adjusters, thread them onto the adjuster screw and
run them to the bottom and back out. Remove from the housing.
14. Now clean the old adjuster ball out of the socket it is broken off in.
I use a pair of needle nose pliers and pinch the tab that is holding the
ball. Then I pry upwards with a pick which usually dislodges the ball
sending it airborne if you are lucky.
15. Install the new adjuster ball in the appropriate socket and reinstall
back into the housing.
16. Obviously installation is the opposite of dismanteling with one twist.
I spend some time removing and cleaning up the rubber sealant that was
holding in the lense to the housing.
17. Before sliding the lense back onto the housing I have found that
heating the housing where contact is made makes sealing it back up easier.
It slides into place easier. I heat it with a paint removing heater/blower.
This is not neccessary but helpful. Don't forget to apply some liberal
amounts of gorilla snot/Wurth trim adhesive in the groove of the housing
before pushing the lens in. This way it will be good and water tight.
18. That's all I got, good luck!

First time though you will spend appx. 4 hours on a set but should get
quicker as you have done a couple and know what you are doing.
