I've had the car in to the garage (at work) & they spent most of the day on it. The error codes were not relevent to the fault I had, but they contacted vauxhall who said there was a technical bulletin out for this problem.
It said to change the small filter on the vacuum pipe that feeds the engine cut off valve, amongst other things.
Also to try disconnecting the vacuum pipe to the engine shut off, although this may lead to the engine 'running on' when its turned off.
So a new filter has been fitted & the vacuum pipe disconnected, & up to yet its been ok.
Fingers crossed
