    my coolant is virtually at max ,cant remember if it happened when it was cold last year but surly if it was a major fault (like the red warning ones are) it shouid show up continuosly and not the very first time you start the car for the day

    Is your car parked on a slope? It has been known for this to give a warning until back on the level.

    Im sure i read somewhere that this was due to a faulty sensor, might be worth doing a search on this.....

    Mine isn't a faulty sensor. I just checked it and the coolant level is low. So I must have a leak. Was fine last time I checked but that was 2 weeks ago.
