Front RHD Passenger Door Won't Open

[willy_manily]

Ok well i went to open my passenger door today on my RHD E53 and when i lifted the handle i heard a flick and nothing opened, its like something has come off from behind the handle and it is pulling nothing when i try to open it.

I am still able to open my passenger door from the inside, it also unlocks and locks fine, but it just won't open from the outside.

Does anybody know what the problem may be, or how i can dismantle the passenger door?

So diagrams and information would be good?
