You remove the VW badge by turning it anti-clockwise.
Then there is a single screw in the centre just below the top.
Then ease out the tabs along the top of the grille - these are easy to see.
Then put two finger inside the bottom openings in the grille and find each of the double tongued tabs.
You need to squeeze the two tongues together by bringing you two fingers together, and ease the grille back.
From memory the there are four of these hidden lower fixings.
If you can take a look at a grille that hasn't been fitted you will see what I mean about the bottom row of fixings.
