clickwir, good luck ive tried everything, with mine. i couldnt take it appart or find a way to get it out, im gonna go to a body shop and get the gti antenna.
but anyway if you try pushing it down and pulling it out, eventually itll stop making that noise, my antenna goes about half way in and thats by force and to get it out i have to pull, i think the car looks nicer with the antenna in anyway, but mine only goes half way so whateva.
good luck
