Great video. I recently did a transmission pan and fluid change on my 2015 535. I was tempted to also do the fluid change on the transfer box but didnt have access to instructions as clear as those you presented (the need to recalibrate the transfer box was new) as well as was somewhat intimidated by the transfer case mounting bracket!😄 I plan to revisit with my next transmission fluid change in 40k miles.
Glad it helped! Removing the mounting bracket wasn't that bad but it does take time and patience, with proper support of the case itself. If the fluid hasn't been replaced lately or you don't know if it has ever been changed, I wouldn't wait too long to change it. Regarding the calibration/reset, it depends on the state of the fluid and sensitivity of the adaptation module. Some had very interesting rides without a reset. Others didn't experience any issue at all. I should have tested the car without a reset first to see how it goes but I missed the opportunity. Will test it next time. :) Ultimately, the module will always relearn and that relearning might be "bumpy" (or take longer) if without a calibration/reset.
@@profsgthe transfer case fluid would have been changed at 34k miles when the case was replaced under warranty. The vehicle is now at 74k miles so hopefully I have some time.
I reached out and confirmed the following scanners support VTG calibration. Product links: 1. Fluid Extractor ($11): amzn.to/4aksDjD 2. LAUNCH X431 Elite BBA scanner ($180, supports transfer case calibration): amzn.to/3TQJ3tX 3. XTool D7 scanner ($350): amzn.to/3wUAHZk 4. Kingbolen K6 Pro scanner ($500): amzn.to/3xa6wxt * Disclosure: As an eBay Partner and Amazon Affiliate, I may be compensated if you make a purchase from the product links I posted in video descriptions and comments.
Official torque specs can be found in BMW repair manuals and TIS. However, people share them on various bimmer forums and this is an example: x3.xbimmers.com/forums/showthread.php?t=1579401
Appreciate the information! Also keep us posted how much you drain from the transfer case under the "oil change mode." I got about 560 millimeters/cc out and am curious about the extra amount trapped when the chamber isn't open. I suspect you would be able to drain 600 cc then.

In this case, I am not so concerned. I am glad about the first change, which is more critical, and you can stretch it a bit for the next one.

Great video sir
Thank you! Glad you liked it.
where do you find the torque specs for all the bolts: Is there a manual we can download and double check?. BTW excellent video and channel.

Also I thought it is better to first use the device to set it into oil change mode before doing this, in order to release more fluid out.
I am not sure about this. Where did you get this information? Happy to look into it if you can share the link/reference.
@profsg I'm trying to send the link but my comment won't post?
