    Default 2008 Vectra C SRI 1.9CDTI 150

    Hi All,

    I have a vectra SRI 1.9 CDTI 2008 150 6speed

    It has 65k miles with Full vauxhall service history.

    Tonight when driving home, when i got home and put the car into neutral. the revs idled at juist over 1,000rpm. So sounds like i have my foot gently pressed on the accelertator, but i dont!

    I turned the car off for 5 minutes and then turned back on and it was idling at about 800rpm as normal. So i then left it on for 5 mins and dipped cluth a few times and then the revs crept up to just over 1,000rpm again.

    No warning lights have come on and its perfomance is fine, such as not restricted etc.

    Ive had the car for 2 years so i know its history etc

    Any ideas whats wrong?

    Possible alternator Ecu detects low voltage so ups the rpm to compensate

    Hi maybe this could be the EGR Valve?

    What do you mean alternator? do you mean this needs replacing?
