    Default Emission light 1.9 cdti 120 helped

    Yesterday when I went to start up my 55 plate veccy with 39k on the clock, the emission light stayed on but went out after I started the car up. Its never done that before. I drove a few miles with no problems. When I went to drive back home the emission light came on again before I started the car. It disappeared after starting the engine again though. It normally goes out at the same time as other lights do. What could this be? Its due a service if thats anything to do with it?

    Where would I read the fault codes? On the screen that displays info like the trip computer etc? Also, how can it be emissions failure without th engine running? I wouldn't have thought it could detect it without the engine running. The weird part for me is it says on until I start up the car, I thought it would be the other way round?

    My dad checked the airfilter and it's fine, after he put it back on the engine management spanner light comes on and stays on with the emission light until I start it and all is ok. Am getting a fault code reader tomorrow so I'll see what it is. It's just wierd how them 2 lights will stay on til I start the car. I know all the warning lights come on when you first turn the key for a few seconds but its just these 2 that stay on.

    If they go out when you have started the car then they show an old code, not a present one.

    Right, got the RAC fault code reader out of argos and it got rid of the spanner light. It isn't detecting anything with the emissions light though and thats still staying on til I start the engine up.

    Did you take note of any code numbers ?

    The emission light (small engine symbol,far right bottom corner) should come on with the ignition (bulb check) and go out when the engine starts.
