Your diff fluid is completely different- The part number I listed is for the 'original' fluid for the differential. The part number you listed is for bmws 'special' oil that is to be used if a customer complains of the differential making noise- There is a bulletin that says if there is a noise complaint, the diff fluid should be changed from the 993 fluid to the 583 fluid. It looks as if you got the special alternate fluid.
For future reference, BMW has different part numbers for different volumes of fluid. This makes is easier for some people and more confusing for others.

I just had my 1200 mile service as well today. My parts description said
20 - 83-22-9-415-961 LSD SYN Diff
20 - 83-22-0-406-582 OIL Manual
These numbers arwe completely different than those mentioned above. How come? My service was done in Canada.
