Hey guys, you all seem to be complaining about the same faults, the cure for this is to use a felt strip tape that VW supply, placing it on the plastics where it is rubbing against another surface! it does work but for how long im not sure! (i just fix them, i dont take them home!! LOL)
And scottish69 - the tailgate trim is probably rattling in your tailgate, theres more than likely a few clips out of place behind the plastic!
Oh and the tapping noise you all complain about, ive never seen this on a golf, but its probably one of the positioning flaps or temperature flap jamming causing it to stick and click!!
