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.
Cheers for your help guys.the garage are saying its something to do with the catalytic converter not functioning so are gna sort it with new cat and gasket.saying its expensive but there doing it as only had car week
