    I've got a 2.6 SE 1996 A4 Avant. When I have the aircon on at a normal 21C Auto the second radiator fan is on all the time at full wack. Is this supposed to happen (even when the outside temp is 2C).

    When this happens the engine temp gauge only reads 80C when up to temperature. If I turn the aircon off altogether the engine runs at a normal 90C because the second fans shuts off.

    Anyone any ideas what it could be ? Does the aircon headunit control the fans or is there a fan control unit like on later A4s ?

    Cheers

    Either your a/c needs recharging (has lost all its gas) or one of the refridgent sensors has gone down (less likely) . Hope this some help .

    The aircon unit does control the fan, mine definatly does. And mine is full of gas and operating properly. Its always done it.
