Getbmwparts advisor - "BMW shows a filling quantity of 2.12L for the rear differential but they do not list a quantity for the front unit. We'd recommend consulting your vehicle owner's manual for that information"

Also I read BMW shutdown Newtis since they don't have latest info.
I found that PN# you were talking about, I think i did an edit at the same time as you posted.

But i've got a newer version of ISTA at home, will check. But from memory it still treated the each chamber separately, with a DO NOT MIX stance.

For my change, i am going to go based on the ISTA/RealOEM info with the 832 Carbon Mod for the packs and 987 for the center section.

Unless someone can link us a bulleting that says we should roll the 972(75W90) into all.
