I still have the pdf from the old site with photos etc of the removal. Can't upload it from work (also can't watch movies) but the steps in the guide are as follows:
1. Open boot and remove caps and then bolts from near the light cluster
2. If you've mud flaps, remove these to expose other screws.
3. There are 3 screws along the wheelarch, one at the top, one lower down and the other underneath. Remove these.
4. There are some plastic clips underneath the bumper in the middle holding the bumper and a plastic undertray together. Remove these clips.
5. Starting at the wheel arches, pop the bumper out and go all the way round and then lift the bumper away from the car.
Replacement is obviously the reverse of this but just watch that you get the plastic undertray up and clipped in before clipping the bumper back in place.
