XDrive Transfer Case Fluid DIY

[skeetjunkie]

Just changed my tfr case fluid today on xDrive ATC 500 unit - simple and quick. Dealer to reset actuator value tomorrow.

This is a also a good time to move the condensation water outlet hose so that it does NOT drip water on the drive shaft just before it enters the transfer box (mentioned in another E53 thread). Loosen the rubber mounting bracket with a 10mm socket, adjust the hose so that it drains directly to the ground and tighten up again. (May wish to do this next time you drain the engine oil?)

I am going to change mine on Thursday, there are some great tips here, but it's easier for me because I have GT1 to recode the car. I am changing the differential oil also..

neilrmp, do you know if Inpa can reset the values also? I have Inpa, but my DIS installation is not functionnal yet, so, I still use Inpa in the meantime.

I haven't used inpa so I would only be guessing, sorry

No, INPA cannot reset the values. Sorry.

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. ;-)

Yup, make sure you reset the values after the change.

Thanks for tip oon the outlet hose. Changed oil on my 2005 4.4 and did the GT1 oil change procedure.

My transfer case is making a whining noise at all speeds but the oil change didn't make a difference although the drained oil was very dirty at 92k miles. There were no metal shavings though as determined by finger feel and running magnet through the drained oil.

I got this error when scanning with my BMW Scanner 1.4.0 today. Oil change itself looks easy enough but dealers around here are the type who would refuse to reset something unless they had done the work, indys not so easy to find.

I take it that BMW Scanner can't reset these adaptation values. If I get GT1 running in a VMware virtual machine is this something I can easily do myself?

Also any specs on the replacement copper washers? Will the dealer parts counter have these or will I have to get elsewhere?

Thanks.

I know this doesn't help - but I am wondering the exact same thing.

I just got BMW scanner 1.4 and picked up the "oil abrasion" error in the transfer-case. The error wouldn't go away when reset. It's in yellow status.

Picked some of the right fluid-up for $44 online and have one of those Romanian scanner gizmos on order. I hope that does the trick as far-as re-setting and relearning the adaptations.

I am getting a little slight vibration when exiting a turn. I guessing the fluid is original with 109k in it. Sounds like it needs a change anyway.
