I thought it was common just coudnt find a sticky on it might be worth doing one I've spoke to lads at Vw body shop theve said take the door actually of then the m10 bolts on the a post easier to get to theres one behind the trim also ie two bolts holding each hinge loosen them then nip one up , put door back on so slight movement in hinge but not to much , then align , then nip um up proper if the hinges have failed stick a socket in the gap and give the door a couple of tweaks
I am not responsible for anything that goes wrong just post some Info that I've been told
