The mk6 wheel doesn't only use the metal clips either side of wheel, when you push it hard into position 4 white plastic locating lugs hold it really tightly in place, so when removing upon twisting the metal clips out, you will need to really give the side your working on a good tug, it will start to come, then when you do the other side, try to keep the first side from clipping itself back in, then wiggle side to side and off it comes, once again it's not just metal clips that hold it in, give it a good wiggle / tug and it will come
