Was fixing a Self Leveling Suspension issue and when the GT1 ran the QUICK TEST (Diagnosis of all the modules) the Transfer case oil value (OLD) came up. My X5 has over 100k on it and I was a little pissed that my Dealership never said anything about this during services when it was under warranty. So I will be changing fluids this weekend. FYI when running through the service schedule, the DIS does have you reset the values as the next step.

Just FYI if anyone in the Clarksville TN (Nashville area ) needs Diagnostics, I have a GT1 an I'm willing to share....though it seems every time i pull that thing out I do get thirsty. ;-)
