well mine when hot has started up and cut out instantly a few times now,although it only does it once or twice then starts fine,then this morning it decided to do it when cold :S (my car has a split breather at the moment"the plastic thing in between the rocker cover and inlet pipe"weather that would make any differance i dont know) hopefully when my replacement turns up and is fitted it wont do it again! otherwise i will be checking: key coding,ignition switch,throttle body,fuses,control box,ecu--not looking forward to it :(ohh and by the way mines probably something else as its a obd2 golf,l
