There are 2 different bleed nipples shown for my 2014 1.4 vrs anyone know which is the one I require (I'll be taking a wheel off next week" but some knowledgeable soul may already have the answer

 

You should be able to see them through the wheels. However, they are not expensive you could buy one or two of each kind. They are usually one kind for the front and the other for the rear and so getting two of each should do all of your calipers eventually.

There's no need to replace them but if you insist then just buy the longer one since it will work in either scenario.
