X3 Fluid Capacities
Aside from the basics like fuel, the Owner's Manual isn't a lot of help to us in determining how much of a particular fluid one needs if they're changing it themselves... :dunno:

I searched the forum, but did not find anything. Do we have anything around here that summarizes all of the fluid capacities of the E83 X3? It would be nice if we had some document/thread that collected all of that kind of information for us.

In particular, I'm looking for the brake fluid capacity (on the vehicles with a manual transmission, if that makes a difference -- I understand that the clutch uses the same fluid system as the brakes). In short: how much replacement fluid is necessary to do the 2-year maintenance cycle for the brake fluid on a manual-transmission E83 X3...? Thanks!

For the ATF its about 8 liters total hold
Transfer case is just under 1L (buy one bottle at dealer for drain and re-fill)
Diffs are probably under 1L each
Brake fluid is probably 3-4 12 oz bottles to do a full flush and re-fill at most.

I'd like the official capacities as well.

+1 on the capacities.
PSU's listed capacities on ATF, TC, Diffs seem about right as I recently did it on my X3.

Does anyone know how much fluid is needed for steering fluid flush?

I use the Amsoil site. But it doesn't list all capacities.
