    Cooling fan problem? Turn on temp?

    Guest-only advertisement. Register or Log In now!
    2011 A4 2.0 What temperature should the cooling fans come on? Scan tool says temp is 215°F and fans still won't come on. I can turn them on with the scan tool, so I know they work. I haven't tried to turn on the a/c because I don't want to rely on the A/C just to control the fans. Anyone had a problem like this?

    105°c seems really high. I'd like to see them turn on at 90°c.

    There's nothing wrong with 105°C. The thermostat doesn't even start opening until 95°C and is fully open around 105°C.
