    Conencted a CReader V.

    Got a P114C

    and P124C (twice)

    The reader says these are manuf specific codes, but when I chose 'BMW' couldn't give more info.

    I googled and eventually found a P114C:

    Post catalytic fuel trim via oxygen sensor too rich (bank 2)

    Couldn't find anything for P124c

    Looked at the 'freeze frame' data for the P124 error - fuel trims were:

    ST Bank1 3.11%
    LT Bank1 -3.13%


    ST Bank2 0.77%
    LT Bank2 -5.77%

    So, does this suggest bank 2 post cat sensor is knackered?

    Which is bank2? Driver or passenger side?

    Help!

    Please.
