So for 5L31 PDC JBBFs over the years (all have same HWEL):

1. 4155104 was used when
a) one of 415/416 and 5DP and none of 205/2TB
b) 508 and no 5DP

2. 4523517, 4525170, 4527813, 2748386, 4125935 were used when
a) 5DP and none of 205/2TB
b) 508 and no 5DP

These are part numbers as were installed in factory. Note, that KIS says type code 5L31 is MECH transmission Or maybe it depends on options, IDK. But then default is MECH

Now replacement part numbers for those parts were (in no specific order, may contain duplicates, have not checked HWELs, could potentially have different conditions of installation):
9312763, 9312764, 9312771, 9312765, 9312768, 9312769, 4155102, 9312766, 4155103, 9345327, 9345322, 9345323, 9345321, 9345326, 4523515, 9345324, 9345329, 4523516, 9353421, 9353418, 9353426, 9353419, 4525169, 9353420, 9353424, 9353423, 4525168, 4527812, 9361120, 9361117, 9361123, 9361118, 9361115, 9361121, 9361116, 4527811, 9384221, 9384219, 9384218, 9384214, 9384215, 9384213, 9384216, 2748385, 2748384, 9393667, 9393669, 9393668, 6822007, 4125934, 9393671, 9393672, 9393666, 4125933, 6992416, 6992421, 6992415, 6992418, 6992423, 6992420, 6992417.
