    hi there ive got a vectra b 2002 2.2 sri150.couple of days ago on way back
    from holiday,after doing 400 miles and getting average 35mpg ,I fuelled up
    at a asda,and from the moment I continued my journey the mpg dropped to
    about 25mpg and this was on the motorway at a steady 70mpg.A day later set
    off for a run and a warning light came on.looked it up in manual and its the
    exhaust ,immobiliser, electronic ignition light.I then refuelled again with
    non asda fuel and im managing to get my mpg back to normal but the warning
    light is still on .any ideas anyone

    Hi Russ
    Had this problem awhile agoand discovered that when i went to Asda the
    petrol has water in it. Ended up having to get a diagnostic check done and
    reset the system again. Hence I never ever use asda again.

    Thanks dereck that's what I was thinking because it happened so quickly
    after fuelling up with asda petrol,got it booked in and prepared for the
    diagnostics rip-off

    Might also be worth waiting till you have got lower on the fuel and run some
    redex through the system, and possibly change the fuel filter.
