    Average MPG at idle??

    Hi, I recently noticed my avergae fuel consumption dropping, like a stone (ie from a long term ave of about 26-28 down to 20 and then a little later 17.6). So I put air in the tyres reset the ave MPG and drove it home, apart from recording very low MPG I noticed the AVE MPG counting down whilst stopped at traffic lights, the decimal places were counting down at a rate of 1 per second. I never watched this before but i feel I have a problem, anybody know if this is normal? If it isn't what could be causing this loss?
    Cheers in advance, I darent take it out at the moment
    Imola S3 looks normal but isn't

    its normal... how can you be getting any miles per gallon when stopped?

    so the computer has e.g 20mpg on it for the last 1 mile journey, you stop at lights for 2 minutes, your using part of that gallon, but not having any miles done.

    i wouldnt worry about it, if you are, you need to lay off the loud pedal a little, or buy a 1.5 diesel corsa :P

    It will drop like that just after having reset the DIS, as claude explains. if you are worried it's change significantly I'd get it at the very least to someone with VAG-COM to check for any faults.

    How many miles are you getting from a tank / has that changed?

    I dont know what I am getting per tank as this has only just happened and I've just filled the tank. Normally I get around 250. Anybody in Kent got Vag Com

    33mpg? Are you sure it's an S3 and not a TDI?

    We've been here before but I pretty much always get over 300miles to a tank, did manage 401.6 but then ran out...

    My journeys are a mixture of motorway and fast A roads, when I managed over 400 that was pretty much all sticking to speed limits on the motorway.
