    You still need the post cat 02 sensor for the fuelling.
    The only way you can run properly without it is with a remap.

    Edit, AEB doesn’t have post cat sensor my apologies.

    P0102 Mass Air Flow (MAF) Circuit Low

    P1198 O2S Heater Circuit Bank 1 Sensor 2 Electrical Malfunction


    P0140 Audi HO2S12 Sensor Circuit No Activity Detected OBDII Engine Light Trouble Code | Engine-Codes.com

    The best approach would be to clear the codes and see which ones come back and deal with them, hopefully some of them will be old and won’t come back.
