I wonder whether some blocks and heads have smaller water passages than others (I assume people suffering problems have checked for furred-up waterways)? I was out in my Seven yesterday (24°C with little wind) and experienced no signs of overheating or fuel vapourisation ... and only realised when I put the car away afterwards that I still had the radiator half-blanked off fro the winter.
