Very slow speed tight turning.
But like I said improved 80% since fluid change.
I went to the nearby independent BMW specialist and he reset the transfer case oil adaptation, but can’t really tell if improved any further.
I’m happy I did the fluid change because before that it was sounding really bad and felt like square back tires almost from all the chunking and clunking.

I read on one forum that some BMW owners recommend to drive ~500 miles after first transfer case fluid replacement and then do another one.
The theory is that there is possibly some gunk left that is still preventing transfer case from operating 100% smoothly.
Once I accumulate those 500 miles may give a shot again to replace fluid again.
In the meantime if you already have 500 miles and plan to do this experiment before me, then please post an update how it went.
Thanks!
