    A3 Coolant Warning

    Hi All,

    My first Audi: an A3 1.8T Sport with DIS (onboard computer)

    We have had a lot of very cold weather as I live directly next to the north
    sea and went to my local VW dealer (nearest Audi dealer is 100+ miles
    away) for advice on long life anti freeze (the red stuff audi uses) and if
    it needed topping up before the onset of winter.

    The ever so friendly mechanic told me that if its servicing was up to date
    then antifreeze should be fine as long as its up to the level (it is).

    Start up the other day .... DIS performs self-check = OK then after couple
    of minutes of running (before I set off) the "Critical Coolant Warning" came
    on - so I switched off and checked the engine.

    Coolant level was fine, coolant temp couldnt be too hot (just switched on
    engine) - any ideas what could have triggered it?

    Any advice for a newbie appreciated.
    Dan.

    Could be the switch thats on the way out or not adjusted properly.

    Exactly the same happened to my wife's -98 A4 Avant 1.6 only days after
    delivery. Dealer took it away on a flatbed truck and performed what they
    described as a "Ctrl-Alt-Del" on the computer. To be absolutely sure they
    changed the sensor for coolant level/temp (?) some months later. We still
    have the car and this problem has never appeared again.

    Thanks for the replies.

    Well the cold (-5C) weather has gone and everything looks fine, have used
    car several times since.

    Its going for a service next week so will have to mention it then. I wonder
    if the very cold weather caused the water to contract and the level to drop
    and as engine got warm it expanded again and came back to level... Who
    knows?!

    Higly unlikely, as you're only talking about -5C. These coolants are
    anyway designed to work in various temperatures, and they should work in
    -40C also. So I'd say you have something wrong in the sensors there.
