So if ptu is under power all the time, the problem would be with the rear differential electronics malfunctioning most likely, or the signal going to the electronics in diff

You could always log the AWD modulation PID, that would tell you it the car is commanding the AWD to engage.

Does livelink/SCT let you watch custom PIDs?  I'm trying to remember from my X3 I had previously but I don't believe you could.  If not you will need to pick up Forscan or use Torque (or something similar) to monitor it.

Ok, no need to log this. The ecu must put the car in fwd when there is low tire pressure. I just got my new wheel today, got the tire swapped over. No more ridiculous spinning of the front wheels. Instantly went away. Can't believe nobody else ever had this issue.

Always a first time!  Good to know, and glad the "issue" is an issue no longer :thumb:

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

Diameter difference must've put it I safe mode. Actually makes sense.

Did the awd off notification pop up?
