Vauxhall Meriva - warning light - gordietfb

Got an odd one with my 2011 Meriva, it's the cdti, great little car but today it the a curved one at me.

The engine management light stays lit after the ignition is toned on and the display does the self test. But start the engine and it goes out, this all started after an episode of the car not starting, I left it for ten minutes and it started fine but the management light nite shows pre engine start.

Vauxhall have said yes it had got a fault but not what it might be and will happily charge me seventy pounds to check.

Any ideas what it may be?
