I think the discrepancy is the front, not the rear.

If you have a E53 or E83 without an N46 engine, you should use a Hypoid Axle Oil G1 which includes the part number for BMW Synthetics OSP 83 22 9 407 768. However, since that isn't the case for an F25, it falls under "All model series and E83 with N46 engine" which is a Hyoid Axle Oil G2 part number 83 22 2 413 511.
Well I have ISTA+ also which is what the Bentley manuals pull their info from and what the BMW dealers used.

I threw in my vin and got this for the front diff:
