My Iveco 35c18 (2010) van has this kind of side door
It closes by inserting these pins
into these 'holes'
However, the door is slightly below its proper position
Here's the upper door axis
And the lower door axis
How can I tune the door so that (1) it goes a little bit higher (and the pins align with the holes) and (2) so that the door shuts a little bit closer to the van (it is leaving a 0.5cm gap, makes it rain inside the van)?
As @ZachMierzejwski says in his comment, it looks like the adjustment is done in the bottom bracket - the three bolts holding the door to the bracket are slotted to allow for height adjustment (it looks like they are sitting on their lowest positions), and the two bolts holding the two parts of the bracket together are also slotted, which would allow some in/out adjustment.
There may also be adjustment possible in the centre mount - the one at the back of the door, which you've not pictured.
Position a trolley jack or bottle jack (or two) under the door, with a couple of blocks of wood to protect it. Take the weight of the door on the jacks, then slacken the bolts. Lift it by the appropriate amount, then tighten them. Check the fit, then repeat as necessary. Repeat for the sideways adjustment...
