Warning heat light????

[Donato]

Steve,

It sounds like your cat might be blocking up... which means the air pump isnt working properly or the cat has used its nine lives...not definite though...

I have an air pump you can have if you need it mate...

Rich check this link, it should answer your questions..

I wouldnt advise removing the air pump until you have decatted the car.

cheers

No idea whats going on now but the light is staying off (well so far) I did not drive the car for 3 days and on the way to work today the light stayed off?

Might be a CAT on the way out. I hope so!!

Same thing happened once my Apexi power FC was fitted, What do people mean by "Knock Warning"

:confused:

After 2 days of driving short distances the heat light is back. Could this be unburnt fuel sitting in the CAT heating up???

If you have no CAT fitted, the sensor that normally detects overheat of the CAT should be taped up and not touching any part of the bodywork, if it does come into contact with the bodywork, it earths the overheat circuit causing the overheat light on the dash to illuminate. I had this problem on mine, it was tucked away underneath the car but when I went over any bumps, the light would flicker on. I taped it up and the problem went away. Maybe this will sort it....

I have this problem only in the wet and under normal driving over bumps etc.
 
Can you please explain where the wiring is located?
 
Thanks
