Hi All,
Just had the Cossie out for a drive for the second (yes-second) time today.
After about 40mins of driving the light came on, not heavy driving as family in the car.
Usual thing, turned engine off when arrived, then when was leaving a short while later started car, light went off, but came on again about 30mins later, but obviously again went off when engine stopped.
Just took car for another drive around my town and light didn't appear at all.

The car is running fine with no misfires, oil pressure fine, turbo spooling fine, basically nothing obvious.

With National Day fast approaching I need to sort this.
Suggestions????
