A word of advice. Change it.
My 2015 X3 has 70k. I'm changing all the drivetrain fluids for the first time. Front and Rear diffs, transfer case and transmission oil and pan. This weekend I started on the diffs.
The rear diff oil was very clean and looked great. The front diff however looked dark and very used. There is no drain plug for the rear so you have to use a siphon like this one that I used:
And to pump it back in:
The front has a drain and fill plug. You do not have to remove the stiffening plate to change the front. I didn't. Make sure you break the fill plug loose first in case you find it is seized.
All fill and drain plugs are a 14mm allen and should be torqued to 60nm.
**Update 1-16-2022**
Front and Rear both now require just under a quart each of Red Line 50104 75W85 GL-5 Gear Oil.
So as of model year 07/2011 the
Rear diff fluids recommended are BMW:
83 22 2 413 512 Hypoid Axle Oil G3 (Fuchs Titan EG 4218)
83 22 2 295 532 Hypoid Axle Oil G1 (BOT448)
And the
Front diff fluid BMW recommends:
83 22 2 413 511 Hypoid Axle Oil G2
Which is also covered by the same:

**Old Original Content, See new information above** Each require just under a quart. I used this for front and rear:
The manual calls for BMW 83 22 9 407 768 and this part number is listed as the direct replacement oil from Red Line for that part number.
