Wait... misread that. I thought it said Adaptive Headlight weren't working. You probably read my answer and was like, is he on crack?

Ok so the AE on the right side of each headlamp arent working? Those rings are controlled by one bulb. So having one ring out on each headlight is odd.

Wait... Unless I am misreading that again. You mean to say, both rings on the Passenger side headlight are out? Or each ring on the right side of both head lights is out? Im gonna go with the earlier. If that is the case, the bulb burned out.

Hahahaha I'm sure you're not smoking crack! Yes, both of Angel Eyes on the passenger side aren't working. If they are controlled by one bulb, then this is no anomaly.

Do you know the bulb number so I can grab one on the way home?

Those bulbs arent readily available at the auto part store. They are a dealer specific item. But before you do that, try switching it with the left side. If it works, then its a bad bulb, if not then it is something that needs more digging.

and this is an opportunity to consider LED, like many of us have had... if you are going for the stock look, then the part is about $20 from a delaer but the bulb is available separately too, you just need to search for it high and low... and separating the bulb and the holder is a delicate task, as the two parts of the housing are fused together via "melted" plastic tabs... once you have the holder out, you will see what i am talking about...

After installing my new trailer hitch and BMW wiring, I walked to the front of the X5 to find that ALL the Angel Eyes are working perfectly. No clue if they are related or if the gremlins are busy at work.

I don't know what to believe anymore..

UPDATE:

Hey everyone, I FINALLY got around to getting to a shop to check codes. Since my last post, the voltage hovers around 13.2-13.4 all the time while driving.

Here are the pics of the codes I got today at the shop. Keep in mind, all my light issues have been fixed. I changed the thermostat last weekend and am due for a transmission fluid change, as you might see in the codes.

Please review the list of codes to see if there is anything that can be extrapolated. My mission by bringing it to the shop was to have them simply "re-calibrate the SAS" and everyone be happy.. The tech said it wouldn't "initialize", whatever that means. Part of me thinks it could be alternator.. Part of me thinks SAS is ACTUALLY bad, which is odd. I paid the $65 today for this list of codes, Please fellas, make the best

Undervoltage code at the top, alternator?

[Buguyed]

You think I should try throwing a new alternator at it? The car is at about 88k miles right now. That's when my 330i desired a new one... Both M54 engines.

I am just hesitant since they OBC reads in an "okay" range, volt wise. My E46 hovers between 13.8-14.2volts.. Maybe it is the alternator.

Its tough to say, but it is a random undervoltage code.

i'm going to check fuse #15 tonight with a voltmeter if I get a chance. It might be wise to just put a new Alternator in. The Alternator/Battery on BMWs generate so flippin many gremlins.
