my 225 has been decatted so the service light keeps coming on. i think i need a dummy oxygen sensing device to hopefully stop this. but where can i get one. or has anyone got another idea to stop this??
I have my car decatted and got the Lambda extender fitted at the same time, engine warning light has never come on so try that, apparently this won't turn your light off straight away but it should after a couple of hundred miles.
