I have removed ALL the bolts from the fender, including head light.
As you can see in the picture I managed to block the fender open, if you see what I mean.
This gave me access to the bolts of the hinges.
However, do not remove or undo the bolts too much, you don't want the door to fall off or move too much.
With the door almost closed, I managed to squeeze the hydraulic jack and lifted it.
It was a case of 3 trials before it was set
As I said, piece of cake
