If its the latter, then you have ACT problems!! (like over 70°!!)

Yes mate it physically goes off just the green backlight stays on. But its hard to believe as my acts are usually around 30c another thing is if i switch of the ignition back off and switch it back on its okay then but will have a look tomorrow and see at what temp the act guage blanks out thanks
