take wheel arch liner out, look round all of wing all bolts and screws are easy to see, including open bonnet and look at bottom of windscreen there is one there, open the door fully there is a torx screw that only needs to be loosened to allow the wing to pull off, some parts are covered in under seal etc so may need a little persuasion to come away from the car. also the 2 bolts behind the front bumper are a bit of a pig if you don't want to loosen the bumper, but if you remove some of the screws for the bumper it will make it easier but not essential. really self explanatory when the arch liner removed.
its a really simple job you should have it off in less than 25 mins with correct tools
