Adaptive Xenon Bulb Change

[Rich H]

So, my passenger side dipped main headlamp bulb has failed.
It is a Xenon bulb in an adaptive fitting.
I haven't found anything to tell me how to change it.
The Manual advises that it is done by MB
I am reluctant to twist and pull at it too much because I can hear the motors that move the beam whirring as the light moves.
Is there a guide somewhere?
Do I just twist it anticlockwise and believe it will release before something breaks?

My dealer changed bulbs FOC, might be worth contacting yours and enquiring?

Just for information.
The cap covering the bulb at the back of the headlamp fitting was also missing, which is probably why the bulb failed.
MB in Stratford upon Avon quoted £221.16 for a bulb and cap including vat and fitting.
I spoke to a local garage that I use quite a bit and got a Phillips bulb, the same as the failed one, that he also fitted for £80.
I will get a cover from eBay for about £20
