    Question Exhaust emission control light ON

    Hi, I have a Zaffi 1.6 2002, the exhaust emission control light is on, it seems the most probable fault is the EGR Valve, if I replace this & it turns out to be the problem will the emissions light go out or will I have to have it eliminated via diagnostic check, dont really want to pay for computer check as they are so expensive. If you think it may be something else then all suggestions would be appreciated.

    I have read that the EGR Valve can be blanked off & you can turn the EGR Valve to the side with one bolt through it & leave the wiring in place and that this method eliminates the need to have the EGR Valve removed from the vehicle computer, is this so? many thanks John

    first off check the code with the pedal test, then if it is the egr valve better off just replacing it with an original delphi unit. and yes once the ecu realises that there is no problem the light should go out. if not try disconnecting the battery for an hour.
