How does the rear license plate holder plastic piece attach to the hatch? I notice that at the top of mine it seems to be falling back. Does it snap into place or do the license plate screws help to hold it in?
Once you get the 4 tabs/grommets off from inside the hatch lid, you can pull it out so the tab surface is beyond the lid. Then slide it down. There is a lip on the bottom of the plastic frame. If you pull it straight off, you'll likely break off the tab/gutter. Mine had double sided tape on it. So took abit of effort to get it off. Not sure if they came that way from the factory.
Chances are the plastic tabs on the backside are broken. They almost all break. It was yet another brilliant and cheap design by VW. There is one that is behind the wing motor and its not easy to reach.
