I'll throw this out to the STW massive unless anyone can suggest a good car/vauxhall/corsa forum.
The wife's Corsa has a problem.
Firstly, when driving, after about 1 mile a warning light comes on. It's a picture of a car with a spanner in it. A quick google shows there is some debate over what this light means but the consensus seems to be an electrical/ecu issue. There are no fault codes logged according to my £10 ebay reader and the man round the corner's £2k machine.
Secondly if it has recently run it'll it start first time. If it has been sat for a while it'll take quite a few cranks to start. It seems the longer it has been sat the longer it needs to spin before it starts (but that might be a red herring). Up to a minute or so if it has been sat for a few days. Firstly it turns without firing, then a bit of almost starting, then it fires up. Sounds a bit like a fuel/air leak issue but I'm really not sure. Could it just be glow plugs?
It's been doing this for a couple of weeks. It's an '03 diesel, CDTI, 1248cc, 70k miles.
