    Hi All,
    New one for me, Audi A2 1.6 BAD.
    Vehicle has MIL on, scanned came back with Nox sensor heated circuit open circuit, both in EOBD and Vin specific. I have looked in the archives and on the net, only info I can find is the nox sensor is after the cat. Can anyone enlighten me to what readings I should be looking at when I finally get underneath it. I guess similar to an O2 sensor?

    Kind regards,
    Nige
