G450 Sensor question

    I have an Audi A4 B7 2tdi 170hp, had the DPF replaced, G450 sensor replaced, EGR valve replaced, and glowplugs replaced around christmas.

    No fault codes after this, just not recently my cars going into limp mode when stepping on it in 2nd and the fault codes read p0472 and p2002

    I believe I read somewhere that I had to code something in the ECU after replacing the G450 sensor but never found anymore information on it

    Thoughts and clues?
    Thanks

    Those are the codes I was getting. Changed sensor about three weeks ago, just swapped over. Seems ok, fingers crossed.

    Think I should try changing it again?

    I just tried re-adapting it with no luck, code is still coming back
