No, the panel is just bolted on from memory, but there may be some plastic rivets attached to the locking mechanism I think, but we don't need to take the whole think off so that isn't a
problem. I replaced an electric window motor clip on my sisters golf and something rings a bell of that rivet....
I'll try and point it out when doing the seals again.
Page 1 of this discussion shows the door panel and all of the bolts. I can take a load of photos when I'm doing it again sure and put it on here. The info on hear is pretty good though! especially the initial post!!!
