    I have a 2001 Audi A3 sport 1.8

    I recently had the o2 sensor (into CAT) changed
    I had the fault codes cleared, and i was good for 2 days

    Now the Engine Management light has re-illuminated itself and after scanning i only get one error:

    P0030 H02S Heater Control Circuit Bank 1 Sensor 1

    Is this the sensor i just changed? Or is the this the front o2 Sensor?

    Either way i would like to resolve this issue and get this light cleared..

    Any help is greatly appreciated :)

    Bank 1 sensor 1 is the pre cat sensor. (nearest the engine)

    Get yourself a vcds cable so you can read the proper vw codes as 'po' numbers are vague, generic and often inaccurate. :)

    Any help on locating this?

    I think this is the VW code: 17524 - Oxygen (Lambda) Sensor Heating; B1 S1

    I had them read prior to this but i have had some bits done since and not had it read properly, but i know i havent had that sensor changed.

    Loads of views but no responses. Someone must know be able to provide a diagram or advise me on how to locate and change?

    As said previously... bank 1 sensor 1 is the pre cat sensor... it will be a wideband sensor as yours is a 2001/AUM... this sensor is between the turbo and the CAT
