Thanks all.
Have managed to fix it, ripped out the handle, leaves a hole, top left of the plate, used a driver to push down the release switch behind the plate and she popped open.
Had to go to VAG dealer to get part (volsapart were out of stock), only cost ?9.30 so not the usual ripoff. Putting new one in was easy, just remember to hold key in the lock tumbler when you cut it out of the old plate.
