You know what i've noticed the fan on before but i must say i haven't noticed it on today. I was on the m1 & i did 145+ mph just after getting back into london. It happened so who knows it might of been that. Thanks for your advice. Did you have you car services yet? If so what was the cost & how many miles did you service it at. If its the fan wiring or something like that i am sure the warrantee should cover it. But why would that light be still on? Hummm.
