The hinges are welded to the body so first make sure they are not ripping off (unlikely). Have you tried lifting the door to see if the play is due to wear in the hinges?
You could try taking a shim out from between the top hinge and the door. If you loosen the 3 torx bolts that secure the hinge then the shims will slide out as they are slotted around the bolts. You can replace the torx bolts with regular M8 bolts if you find them easier to work with.
