Hi guys ,just realised that my passenger rear door doesn't open.it seems that the little black button doesntb quite go fully up.i can open it manually from the inside but not externally .any ideas ?regards in advance

based on experience, I would say its down to the outside temperature, will free up when warm  2013 L405 Autobiography Baltic Blue
2007 L322 Vogue Buckingham Blue

Ours is the same.
I spent a lot of time on the search button last night and read most of the posts ref doors not unlocking
I came to the conclusion that it's prob the unit, they aren't expensive by the look of it
But some one posted about a large squirt of wd40 down the button did the trick
So I thought I'd do this first
But when I looked I decided I needed to remove the black clip around the button to do it
It was then I saw the button was slightly bent towards the centre of the car and was almost jammed against the circular clip
Should it be angled or has it got twisted somehow or bent ?
But I did give it a soaking and for the time being left off the clip
It now opens and shuts every time
If anyone's got some pics of the door internals with the card off I'd love to see them
Cheers

Cheers guys ,ill try the wd40 route and remove the outer black cover and see how we go from there .again many thanks.
