Sorry. Haven't done it myself but I watched the guy who fitted my towbar so that I would know when I fit my reversing sensor. It's very simple. When you have the screws removed from the wheel arches you simply hold the bumper with both hands and pull it away from the car to the side. It will simply pull out of the clips. Don't be a fraid to pull a bit hard. You shouldn't break anthing. Onece both sides have been freed from the car you can then remove the whole bumper by pulling it from the back of the car. It's probably best to have someone else help so that don't drop it and scratch the paint. A piece of old carpet it good for laying it on. Good luck.
