The numbers after the decimal point are simply a revision number (how new it is only). It is the numbers before the decimal point that indicate what program you have.
AV10231 is the program for the newer style DPF cans and replaces program AV10137. Look on the ECM and verify the E/C number is AV10137.?? or AV10231.?? - If it is, then you have the correct program for that engine.
