XDrive Oil Change, Adaptation reset before and after experience

[TriX5]

Sorry if I am missing something, but if the system is adaptive, would it not over time re-adapt to any new condition? I thought the whole idea about that was that it would monitor its own condition to set paramaters, but maybe I am just not understanding something.

Oil Monitoring is performed by the VTG control module to determine when a service
(change) is due. The VTG calculates transfer case and clutch wear based on the amount
of slip, engagement pressure (torque), speed and mileage.
This calculation accounts for normal “dry” road driving, “adverse” road driving and
“other” road extreme driving. Depending on individual vehicle use - driving styles and
driving conditions, the transfer case oil service interval will vary.
When a service is due, this will be indicated by a Fault Code and additional details are
available using the DISplus/ GT1. Service functions provide directions on changing the
transfer case oil and updating the VTG control module with the necessary reset and

adaption procedure. This is extremely important for CBS.

I've been driving around a bit now, It could be in my head too but i still say that it feels a tiny bit smoother.

Otherwise everything else about it feels about the same as it always has been now. It was a bit different straight after the reset, but it seems to have adapted very quickly back to how it always felt.

which i'm hoping is a good thing. Especially after JCL who made me realize that i could have failing clutch plates I guess time will tell. Thanks though JCL, I never thought of that, I still have the old fluid so i'm going to check it for any bits of metal etc.

SlickGT1, everybody that changes this fluid seems to complain about how black it is, I think it's pretty normal being so black, The smell is the giveaway. and the new magnetic bolts are probably there to catch metal shavings.
