what is the mileage?
change the fluid if it hasn't been changed.

Well that's interesting!! I really hope it's just he fluid. My car is at 66,500 Km.
I do put a trickle charger on the once/week though so I wouldn't think it would be the alternator?

The alternator has nothing to do with the trickle charger. Are you running standard size tyres?

Ah...well then, good to know. Yeh standard sizes with the 20" 469s.

How do I get the voltage to stabilize??

How do you know it is not stabilized?

Well, I'm just going by what you said in your initial comment that your issue went away after your voltage stabilized. If that ends up being my problem as well, I just want to know how you got yours to stabilize.

The electromagnetic actuator inside is extremely sensitive and often a simple oil change and recalibration is all that is needed but a dealer only makes 300 off an oil change vs 7 grand for a new transfer case so you know which one they will choose unless you ask...

This is exactly what I did and the problem is gone. There's friction modifier in the fluid of these transfer cases. They wanted to sell me a $7,000 transfer case and I got out of there for 550 bucks which is still outrageous to change the fluid.

Luckily mine was covered under extended warranty. Paid for the whole thing itself lol. They tried to put in a used one too. I refused and told them I'll just wait as I pull the fuse to stop the jerking. Took a month to come in from Germany. Agree these should not be lifetime fluid. But bmw is suffering not my check book.
