Factory HID headlamp adjustment

[KJA2001]

Has anyone had to adjust original HID low beam headlight on the Roadster? Mine has the left side set too low. There is a single long metal adjustment screw with 6mm hex head (very different from non HID units). I managed to raise the beam a few degrees but then the adjuster clicked, the beam dropped again and now it does nothing, turning either way.
Any ideas? I suspect that I am going to have to take the unit right out and possibly change some shims.

That is the only adjustment screw. It attaches to plastic piece that snaps into the light housing. Sounds like yours broke or popped out.

Thanks. How do you get to that view? Is this a lens off job?

That pic is with the lens off. You can see it if you remove the rubber cap used for bulb replacement, but there is not much room to do any repair.
