Hi. Does this differential fluid also go in transfer case of BMW 2012 X5 35d.

This fluid is not for the transfer case.

Hi. Is this for rear gear differencial auto transmition too ??

Doing a manual swap (420g getrag) on my 540i is this suitable for my tranny swap?

You will need to check the sticker on the side of the donor transmission. It may need ATF or MTF LT-2, if it needs MTF LT-2 this fluid is suitable.

Where can I find the differential fluid drain fill plug/bolt? 2011 Mercedes e350 sedan base model.

The drain and fill plugs are on the right side of the differential.

I noticed it mentioned not for use in limited slip differentials. I have a '08 bmw 128i with the stock diff as far as I know. Is this fine to use? I am unsure if my diff is limited slip or not.

Your 128i does not have a limited-slip differential from the factory, this is the correct fluid for your vehicle.
