Heat light

[gmogle]

Guys,
Gave the car a service yesterday and now the red heat light has come on. I dint have a cat in the car.

Any ideas please ?

Cheers,
Gareth

assuming you have a PFC, the heat light coming on indicates a sensor failure.

Could be something nice, (air temp sensor), or something much, much worse (OMP).

Get a commander and check the fault page.

could just be a dodgy wiring job / earth fault under the car where the cat used to be?
