[MG ZS STE]

Thanks James, that's a good shout. In the thread I read on XPF the guy had said he had only unplugged his and it had stopped the fault reoccurring. He hadn't replaced the canister in his last post, but was on the hunt for a new one. He never did update to say whether it had or haven't cured it long term. It was only a long shot, I have read that they can get flooded with fuel if you over fill the tank and take a sharp right turn. Also, if the car has been in an accident (which this one has) the brick can crack making it no longer effective. And as it does form part of the emissions thought worth a shot.

The coolant seems pretty accurate on the scangauge. The needle sits just below half way and barely moves between 90 and 100 centigrade. fans kick in around high nineties upto a hundred bringing it back to 90ish.

I was watching the open close loop cycle on the way home. It stays open on idle, closed when cruising, open when accelerating and slowing down in gear. Will check if when the light comes back on if it stays in closed loop, as it could be chafed wire in the loom?
