How easy is it to take a bumper off a Polo 6n? Helppppppp 
From memory, not that hard, just takes some time.
Remove all the screws from the front of the arch liner, remove some screws from under the grill and maybe lower grills too.
It's been 7 years since I sold my GTI so I don't remember where all the screws are, but you'll work it out.
Get an old sleeping bag or something ready, so you can rest the bumper on it once you've got it off!
