    Hi,

    Since its started to get cold, every morning I start the car up in my garage the [​IMG] light flashes up on the dash... it's then gone after about 90 seconds of the car idling. is this a problem or just the fact the coolant would be quite cold on first start up due to the weather.

    Cars running spot on no problems I can notice, just this dam light keeps bugging me in the morning.

    There is another thread on here recently been started for the same problem.

    When I used to get this with my A3 'only on cold mornings' it turned out to be the metal prong that measures the coolant inside the bottle, it gets coroded over time, simply remove and clean up with wet and dry/ soft sand paper and it should cure the problem...
