My VW was missing the upper part of the mat holder and I could not find anything on how to remove the floor mat clip that is attached to the carpet (not the floor mat it self). So what I ended up doing was go to my local pick-n-pull junk yard and cut out some clips from some old beat-up VW. I took the clips with the carpet attached home and tried to figure it out. It turns out that the clips are pressed onto the bottom holder that is on the underside of the carpet. They would not twist off or thread off so I finally figured out what to do. If you stick a screw driver between the the top clip and the carpet and twist it around and rotate it on the sides of the upper clip it will eventually come off the bottom holder. Now with the upper clip off I was able to push it onto the location that it was missing from VW. Sorry for the length, but I hope this helps someone.
