Adaptive Headlight Left/Right Swivel Error

Good Morning!!

This morning I went to drive out on my way to work and as soon as I turned the wheel, I got a Headlight Error. I'm assuming it's the swivel function as it showed the Headlight facing up with arrows pointing left and right. This was confirmed when my headlights aren't following my steering wheel. The Green Dot next to the Headlight Switch is still lit up and my headlights still auto-level, but just not pivoting left or right. I haven't had a chance to run my BimmerGeeks ProTools Scan tool on it yet, but I was hoping maybe someone knew where to look for this problem. When I take my lunch I will run the scan on it to see what it says, but I think the Error this morning says it all. I did turn the car off and restart it so I know that the Auto-Level function still works which is why I'm a little confused.\

Any input, comments or advice would be greatly appreciated. Thanks!!

OK, I ran the scan and this is what I came up with. Hopefully this can give someone an idea of what I'm looking for and how to fix it.

Looks like the stepper motor controller module, which is located under the headlight housing is bad

I considered that it might be that, but didn't know exactly where it was. I just haven't had the time to pull it apart to verify this. But at least I managed to code it out so I don't get the alert on my dash anymore until I get it taken care of.

Thanks for the input!!
