That aint normal mate.
When all VW's leave the plants they have a polystyrene block stuck to that part of the door to prevent chips when opening doors close to other cars. I have unfortunately seen this damage several times. It's caused by a door being swung open onto something so it bends the door edge but doesn't damage the paint because of the polystyrene. Very poor of your dealer not to spot it. Good news is it's an easy fix. You won't want to watch them do it though. Pair of pliers with rubber wrapped over the blade and bend back the other way. You can do it yourself but sod it!, get you dealer to sort it, they bent it!
