I noticed I'm missing fuse 123. Can anybody check to see if they have that one empty?

Anybody think this "fuse" has anything to do with my problem? doesnt look like it serviceable.

It's not mine, I just used it as a reference. Found it on google.

Here is a picture of my trunk fuse panel. Hopefully this helps. Keep in mind, if your X has different options than mine, there may be fuse differences. But at least this will give you a starting point.

Yes, I suspect a power problem. BMW-Planet.net(?) has wiring diagrams that might help identify the correct fuses and should tell if the fuses on top of the battery are involved. These diagrams are only thru 2008 I think, but I suspect X-drive power distribution for newer models will be similar. These diagrams are viewable on Win10, but installation is involved. You need to load & config Java, load svg viewer.

On the right side of the fuse box is a drawing that shows what the fuses power. Open it and look for 4x4/DTC/AWD/X-Drive etc.
Did you check the fuse box under/behind the glovebox?

The '08 transfer case is powered by F92(25a) and F125(5a). Both of these get power from F172 on top of battery. With engine running, check F92 & F125 fuses for power w/DMM.

Indeed was a power problem. Ended up being fuse 92 (25a). Late reply, but thanks a lot, saved me a trip to the stealer. Glad I have AWD in this Chicago weather @ snow
