they can be a pain to get out but they do push out. be careful you don't snap a pin on the VW one though.
A good spray of WD40 as lube helps too, or fairy liquid. Also try warming them up as this helps reduce the brittleness of the plastic.
sweet cheers mate, going to go and have a go now as its supposed to be the warmest day in a while here!
Basically Lube it up, pull gently, and hope they pop off, gotcha! Cheers guys!
