Hi Thanks for your quick response. The red temp light is to the bottom right of the temp gauge. I know it should light and then go out as with the STOP light and both do 99% of the time. Just twice from cold these two lights appear not to be in sync with the others that go out when they should. It drives fine, coolant fine. A glitch I suspect. A very nice and practicle estate I hope to keep for a good few years.
