I suffered the Jammed Bonnet problem twice in 6 months although I had Cable tied the Junction Box & regularly greased the Bonnet Locks.
On checking a little further I found that the two retaining bolts on each Bonnet Lock were tightened so that the rotating discs inside were very stiff. As an exercise I tightened these bolts a little further & found that this completely seized the locks so that no amount of pulling on the handle would activate the locks.
The remedy was to set the bolts at a low torque & apply Nutloc so that they will not move, the locks now rotate very easily.
I suspect that these bolts were torqued up the same as the 13 that retain the Grille to the Slam Panel on build,as I purchased the car new & had never had reason to touch these previously. I think this could contribute to the high incidence of Jammed Bonnets we see reported.
If these bolts are overtightened no amount of greasing will overcome the problem.
