Is it rust or has the weld come away from the door pillar if weld has cracked its a easy fix with a mig welder not stick plant as it will disintigrate the pillar,can be done with the door still attached,open door to its limit and put a tack on the top and bottom of the angle then carefully close the door to make sure its lined up and not catching anything if its ok weld it where cracked and put a small stitch along the top of the angle ,ive done this on both my doors its a common fault especally on the estate models :rolleyes: .paul.
