    Engine : 1,9 cdti 150

    Year : 2005

    Default Exhaust Emission light wont go out!

    Hi everyone, hopefully ive put this thread in the right place. Ive just bought a 05 sri cdti 1.9 which has done 80,000 and the exhaust emission light on the dash is constantly on. The car drives great, plus the garage i bought it from checked it on their computer and found no known faults. They even reset everything, and surprise surprise the light came back. I read that it could be the EGR valve is dirty, but the garage said theyve given a car a once over plus a full service and MOT before selling it to me, and they said it might be a fault with the dashboard light. I have 3 months warranty on the car. Can anyone suggest what the problem might be? Loose wiring??? maybe. Im just guessing, this is my 1st vectra so im new to vauhallls.

    EGR Valve is the first thing I'd say look at. Don't pay attention to what they tell you. If the valve has failed - ie not opening is will cause the light to come on.

    They said they checked the EGR valve and gave it a clean. Thats after i read on this forum about the EGR VALVE been connected to the EXHAUST EMISSION light been constantly on, and asked them about the EGR. Im not one to have a go at cleaning them myself (even though it looks straightforward on youtube) so i might aswell take it back to get sorted seeing i have 3 months warranty with them. Ive only just had the car this weekend, so ill see how it is after this week. Ive only driven 50 miles in it so far, so hopefully nothing drastic happens to the car

    Get it back to them as it's £200 you don't need to be spending if that is the fault. In fact get them to chage it.

    Pedal test doesn't work on the 1.9CDTI's.
