push the tailgate firmly so that it is shut, then give it a sharp rap with the heel of your fist to the left of the raised number plate light cover, then pull up the tailgate as you would normally. It should open. This is a common fault unfortunately. Mine fixed itself after several months of the same problem. However. Mine refused to start today, even though the fuel and electrics are fine. The garage is baffled.
