I found some posts on another board (you know which one) about a "new" differential fluid or additive for the diffs in the M3. I seem to remember something about TSB about changing the fluid.

The part number I have is 83-22-2-282-583. My dealer parts people are saying that it is the same as gthe old fluid, just in 1L versus 55L container.

Anybody able to shed light on this for me? Maybe the TSB if there is one?

If it is a new fluid, I want to get it changed this week when the car is in for the replacement pedal (sticky accelerator).

i really think it's a new fluid, but don't have any better info than others

the old fluid was:

CORRECT Diff Fluid:
p/n 83-22-1-470-080 (55L container)
p/n 83-22-1-467-993 (1L container)
