Transfer Case and Front and Rear Differential Service

[Bmwe5320023.0]

I just replaced the trans fluid and transfer case fluid.

From reading this thread, looks like I can't reset transfer case adaptations with INPA? That sucks, I'll try to figure it out with ISTA or DIS.

Now for the transmission, it seems pretty easy to reset adaptations with INPA. However in the article I found, it says a relearn procedure must be done following adaptations reset.
The procedure looks like a big headache

Granted they're talking about a different 6 speed transmission, but I wonder if anything like this is required for a5s 390r?
