if you can hear the solenoid clicking when you press the button I'd say the catch just needs a little lubrication
so I'd 1st try using the manual release to open the hood and then apply some general purpose grease to the catch and hook
if this doesn't help then check that the catch moves with the hood open and when your assistant presses the button
the solenoid should pull the latch directly to allow the hood to 'pop'
so I'd say that its likely to be a broken plastic link on the catch
the whole catch assembly will have to be replaced
Sorry I don't have that data
