New VWs use plastic caps to cover the lug bolts. They look great but are a challenge to remove. If you try using a screwdriver you can damage the caps or the wheels themselves.
Luckily VW makes a small tool that makes popping these caps off a breese. VWs came from the factory with this removal tool, but, we have all lost ours by now (you can blame it on the previous owner if you'd like). Get a few spares (one for the car, one for the toolbox, and hide one for later)...you'll need them.
