Start with the bottom bolt, underneath the wing, will be a 13mm bolt, undo that 1st.
Next you have to remove the front bumper to gain access to the next bolt, a 10mm bolt holding the wing to the bracket.
Next, is a 10mm nut inside the arch, may have to remove arch lining and its by the door side.
Next, 3 bolts at the top, open the bonnet and 3 10mm nuts, unto them.
The wing may stick abit but just give it abit of a pull and it will come off.
