According to the owner's manual, you're supposed to be able to open the boot by pressing the button on the 'key fob thing' .... without unlocking the whole car (as did our R53)
Our's doesn't

and the dealer reckons it's now been disabled in the factory on newer models because of all the numbnuts who locked their keys in the boot

Anybody else heard / know of this .... or are they pulling the wool?
