All of this is for the Z4M
First things first, here are the links you need to get a visual of the areas you're going to be working on.

Some helpful info:
1) i used 3 bottles of this:

2) i used two bottles of this:

3) you're going to need 2 diff plugs and 2 trans plugs as they are one time use:

4) there have been problems for some people in accessing the upper trans plug, i planned ahead and used these:

all one piece and were the highest quality hex sockets ive seen. Here's the important part, they are also very stubby compared to all the other ones ive seen and owned.
5) you're going to need a pump of some sort to get the fluid in the trans and the diff. I used this:

Works well, just be sure to pump slowly. Too fast and you're just going to tire yourself out and blow the hose out several times (ask me how i know).
Finally, the torque specs on the website are in NM, my torque wrench only has specs for lb/ft so here are some conversions for you:
Diff drain plug: 48 lb/ft
Diff fill plug: 45 lb/ft
Trans drain and fill plug: 26 lb/ft
be sure to lay something under your oil collector because it makes a huge mess if you aren't careful.
Last bit, all you need to do to get to the diff is remove the flimsy aluminum shield thing from around the resonator and the diff. Its like 7 8mm screws if i remember correctly.
Good luck and happy motoring!
