You have four large torx bolts when I say large , they only have a small Torx 30 size, just penny washer type heads going round the front next to the grille,take the plastic wheel arch self tappers out that are near the front of the arch, including the square protection cover and screws,take off sqarish protection on the innerwing in the wheel arch and peel back plastic arch so that you can access the bolts also torx 30 that secures bumper to wing, there are three each side do same other wing then there are four more torx bolts going up the way round the front, not sure if this releases the belly plate as I don`t have one fitted.
Now before the last two torx bolts come out,try and release the fog light feed wire, and the headlight washer feed pipe it joins at the drivers side front and you can unclip this by sliding the moveable clip off ,it does not come right off just allows the pipe to separate and move the bumper away from the car !------------I THINK!
