Remove your front grille completely....Get your hand up and inside below the slam panel. You,ll find the end of the release cable or you should find the bar if the cable has ripped out complete. Just move the bar to the left and it unlocks the bonnet.

i have a spare wheel on my bonnet so the release cable does jack all. i just put my hand into a small hole in my front grill and move the lever to relase
