Thank-you very much for replying. I went to a garage yesterday and booked it in for this morning, they said it would be ok to drive. The lights have now gone off but I havent driven it anywhere of substance to see if its over heating again, the guy at the garage said its ok to drive it, he only checked the water level and petrol bit, he said it may have been a sensor but Im really nervous driving it as I dont know what was wrong. Another guy from work said just to sell it but I dont want to sell my car or pass the problem onto some-one else!
Is this something that normally happens or is it likely to over heat again? I'm sorry to ask again!
Also how do i check the coolant level please? I know a little bit about cars but only from what has gone wrong with previous cars.
