Xenon Headlights: Removing leveling motor

[James28]

On my passenger headlight, the plastic casing on the inside that holds the bulbs is loose and swings up and down.
I've figured its probably to do with the headlight leveling motor (black box between the two rubber covers on back of headlight)

How do you remove this?
Looking at it, it looks like it twists, and can only twist one way. But no matter how hard I twist it'll only turn a tiny bit, and I can't remove it.
Any tips?

Scrap that, I've done it. Just twisted really hard!
Now to see if I can find the issue, as it failed its MOT on headlight levels.

IIRC, it needs to be 'un-clipped' internally before it can be removed. There are nodules on the outside of the motor casing which fit into the keyed lip on the headlight, once the arm is detached internally you can then twist the module to it's unlocked position and pull it away. Might be worth keeping in mind when refitting as the arm sits inside a joint which allows it to push and pull the reflector.
