A few times over the last couple of days when the wife has been driving her car, the choke warning light has come on for a few seconds and then gone off again.

The car has no choke as it's fuel injection!

Does the choke warning light on the dash have some other function on an EFI engine as fitted to this specific car? The manual for the car has no information except to say 'only applicable to certain models'. Funnily enough, the 1.4 engine isn't even mentioned in the manual for this car!

No other warning lights or problems noted.
