I left my car at the MOT station this morning and they just called to say that they left the car running for 10 minutes and the water boiled out of the cooling system. The temp gauge was at 90 so it hadn't overheated? The emissions is the first part of the test so it has to be left running for the engine to get warm. They're going to refill the system and try again but otherwise the test is cancelled 
Any ideas whats caused this? I left it running for 5 minutes or so when bleeding the PS system and there were no problems, saying that the weather was a bit cooler than it is now...
