    I don't know where the sensor is, but assuming it's not an expensive item I wouldn't think it's too much of a job.

    Haha.

    The oxygen sensors are <£100 - get on Eurocarparts and have a look. Least its not the Nox sensor as thats >£200.

    iirc my fsi has 6 exhaust sensors! 2 up at manifold, 2 in front of the cats and 2 after the cats. Not sure what the 2 at the manifold are for. You need to see what the scan said. Will tell you which bank and if its upstream or downstream of the cats.
