Exclamation Adaptive Headlight Problems

Alrighty, I need some help from my fellow BMW owners. I've got an 08 335 and about a week ago my passenger side adaptive headlight stopped working. Both of my actual Xenon lights still work and when you turn the car on, both sides still auto level (the lights move vertically up and down.)

However, the lights do not move horizontally, sweep side-to-side. ( The driver side light does move side-to-side but bc of the error on the passenger side, the system disables it.) Took it to the dealership, my first mistake, and they weren't much help other then telling me that my passenger side light was having problems and they wanted to charge me more money to find out why.

Next, went to BMW repair place and they got deeper into it. They determined there was no condensation inside the light, or corrosion issue. They ordered a new SMC and FRM but turns out both of those were working too. My mechanic is puzzled because he says that when they send commands to the busted light, they can see it trying to turn left or right but then its as if its gets stuck or hung up on something.

Any ideas what would cause this? Maybe the rod that moves the right side is busted or dislodged? Is there anyway that I can check that other then removing the bumper? They are saying the only option at this point is to put in a whole new headlamp unit, which I can get for about $650 off eBay. But if its something simple, I'd obviously rather do that. Thanks for the help!
