My doors are really noisy. it sounds like all the parts in the door are loose. and the central locking is really loud.
the rubber bushing/pads at the bottom of the door are intact.
any suggestions ?
Same here on the locks. My wife's 2002 New Beetle is almost silent at locking. Mine sound like they're activated by shotgun shell loads.
Regarding the door sound, there are a series (10?) of 10mm bolts that hold the window regulator panel to the door. If someone removed/replaced the regulator assy or had to get into it for some reason and didn't snug up those bolts, you might hear rattling from that. In any case, you'll probably have to remove the door panel (look for instructions on repairing the window assy, they'll be in there) and take a look at the window regulator panel and also make sure all the stuff (speaker, window motor, regulator assy rivets, etc) are all in place and tight.
