Thanks guys... You're not filling me with much confidence
I didn't see any lights on at all. I didn't notice the temperature gauge but then I wasn't really looking at it. As soon as I got out of the car though I heard the fan going which I don't normally get, then the running liquid (oil) noise and quite a bit of white smoke which lasted about 5 mins from the vents. I guess the preferred option then is do NOT drive it to my mechanic!!!
