any ideas

 

Sounds like maybe the sensor wiring is faulty/cracked?

 

When you say 'Blanks out', do you mean that it physically goes off or the display goes to ' - - - '??

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

 

its the second ive had and its still doing it

 

I can't understand the link between it going off when you make boost?

 

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

 

pace intercooler?

 

I would check the probe.

Long shot, but maybe the end is bare and when you make boost it pushes the bare end onto a metal surface that shorts it out?

Is the Temp probe in a Plastic Elbow? Or is it under a Hose?

 

That's what I meant C, the boost moving/pushing the probe and causing the break.

 

Hi mate the probes in between the hose and charge carrier and yeah you could be right will have a look tomorrow does make sense to as the more i boost the car hard the more it keeps on switching off cheers
