Have you got fuel in it, if so then sounds like the immob is cutting in maybe.
Defo not the immob as it's not activated. Is it possible it's the dizzy?
could be a lot of things shady, and over the net fault finding is never easy, take it no Breakdown cover ? best get that sorted if your getting a mk4 
Did have breakdown cover but didn't renew, should of really lol! Bloody hell.
Okay I'll have to just wait for now as I'm meant to be going out today, and got things to do so will leave the car alone, see what happens. Maybe it'll spring back to life, and don't worry, chuff, I'll be sure to get cover on the MK4 lol!
I doubt the spark plugs are faulty as they are only a year old.
