    My S3 has recently started playing up. It only seems to be when i pop into a shop or something and want to restart it again after only a couple of minutes. Also the fuel economy has dropped slightly.
    I am assuming this is due to some temperature unit telling the car its cold all the time and therefore flooding the engine on restart. Can anyone give me more of a specific idea of what is going on????

    Does your coolant temp gauge get up to 90 degrees and stay there? If not you might have a temp sensor or thermostat problem.

    Yes temp goes to 90 degrees and stays there just fine.

    I had the same issue, i'd say its the pre cat lambda sensor, does it smell a little rich and perform a bit poor when its cold?

    It definately floods when starting from warm, runs lumpy until fuel clears.
