hey mate!
for one if its still under 3 years dont leave this any longer. Its still in the warranty time i would be demanding even if they class it as a "wear and tear" they replace it now! or fix whatever problem is. who have you been speaking to @ VW? if just the servicing person demand someone higher. if no better then just go to the director of the branch/region. See whats said but if nothing else threaten with going to auto express and some major magazines about the problem. possibly speak with VW uk as my past experience the dealers lie through there teeth to what they should be doing. if your in the finance where you baloon payment you can always just give them the car back? worry over to which surely they would be replacing this "fault" before putting it into there "approved used" anyway which would question why they are so reluctant to do it under your warranty... 
Thanks very much for your reply

The service guy said to ring a month before my warranty ends and "we will go from there" I said to him its shocking that a car of this age, price and mileage is having this kinna issue and he just kinna nodded at me lol you have a point there if i was to hand the car back, they would have to fix it anyway before they sold it on, surely it would be easier for them to do it under my warranty as they can claim this back from head office?
I was planning on paying the final payment and keeping the car but this issue is putting me off + it has developed 2 or 3 really annoying creaks/rattles

Suppose i have a few months to decide lol
