Temperature gauge warning light on cold start

imported_monkeytrousers Oct 25, 2004

  1. Hello

    Now and again, over the last few weeks, when starting my S3 from cold I get beeps and a "temperature gauge" warning light on the Drivers Information System.

    If I switch the engine off and restart it doesn't come back, or if I ignore it it goes away after a few seconds.

    Do you think this is indicating a genuine problem? I've heard that S3 warning lights can sometimes come on for no reason.

    Anyone else had this?

    I've got the same problem. I did a bit of search and I'm hoping this is the answer...


    Hope this helps.

  3. Yes, mine is fixed since I put a little water in. I never get the warning now. Easy does it - you only need to add a little - 1-2mm above the max line.

    Thought I'd let you know that when I phoned Audi about this problem they agreed it was common, but it did not need a new header tank.

    All I needed to do was add a cupful of water to the reservoir.

    In the cold weather, the water level can fall just below the minimum level, which triggers the warning light.

    In this case a cupful of water meant it no longer sank below minimum when cold and the problem went away.
