    Vehicle : Signum

    Trim : Elite

    Engine : 3.2 v6

    Year : 2004

    Mileage : 110,000

    Default Engine management system

    Got a problem with a 2001 Vectra-b 2.0dti estate.
    The engine management light comes on, sometimes after1/2 mile sometimes after as much as 5 miles before it comes on. I have taken the air filter out and so far no light has come on, but can not get full revs. does anyone have any ideas or know of a specific Vectra-b site?

    MAF would be a good starting point, if removing the air filter seems to cure the fault.

    what you need is a session on the code reader while it's giving that fault light to pinpoint it..

    For vectra b specific help, try vectra-sport... 2nd home of green growler..

    Thanks guys.

    I put a bottle of Redex diesel cleaner through system and changed air filter, took air sensor off and cleaned it with cotton buds and nail varnish remover, and as if by magic it seems to be all right after covering a distance of 20 miles. I am now getting full revs 5000 without having to put the throttle all the way down.

    So far so good. I use it quite often for cleaning things if i cant get white spirits or petrol. It usually works if it can remove nail varnish then it will remove almost anything else, you just have to be careful.
