BMW X3 Transfer Case Fluid Replacement Service DIY (2011-2017 F25 BMW X3 xDrive28i, xDrive35i)

►As the owner of a BMW X3, you'll eventually need to replace its transfer case fluid. The transfer case is bolted to the back of the transmission and sends engine power forward to the front differential via a few chains and sprockets. A special lubricating oil is used inside to keep all the moving components happy and cool, but it wears over time, significantly reducing its effectiveness. BMW recommends a replacement every 30,000 for long, trouble-free usage.
Replacing your BMW X3's transfer case fluid is a relatively straightforward process requiring only a few tools and some fresh fluid. It'll save you some money, too, as the cost of some fluid and an hour of your time is much less expensive than a few hours at a dealership or independent shop.
Wrench along with Mike Hidalgo, FCP Euro's Professional DIY'er, as he replaces the transfer case fluid on a BMW X3 F25.

A 4Matic Mercedes transfer case fluid change DIY like this one would be pretty great. Especially for the W205 or X253...hint hint👀
Actually, more mercedes DIYs on either of those platforms would be greatly appreciated😅

[@nevrcm3261]

the forgotten fluid change...doing mine this weekend

[@fcpeuro]

Wooooh!

[@oldjarhead1125]

As mentioned below by ashedkins, it's my understanding that adaptation reset is no longer specified my BMW. Can you comment on this? Greetings from the Old Jarhead from WNC

[@brarautorepairs]

I would still do it after the transfer case fluid is replaced. It actually fixed a shutter I had under hard acceleration

[@ashedkins]

Does this need the "adaptations" resetting after the oil change?

[@jayparnes]

That’s a good question. My scanner provides this function for my E60 but not my F30. So I had my shop do the F30 fluid change and they said that nothing came up to do this reset. So bmw could have changed their protocol.

[@invertedpolarity6890]

In the description, it says this is applicable to the 2013 X5 which I have. And you do indeed need to reset the adaptation for the transfer case. I used ProTool for doing this.

[@nevrcm3261]

is there a adaptations reset for when either differential fluid is changed? If no, then I assume the same for transfer case. this is a chain on two sprockets (rear drive connecting to front drive) (th-cam.com/video/LtSMdmqZ9Bc/w-d-xo.htmlsi=JP6IgjepthGNoRDi&t=641).

[@profsg]

Yes. Check out this video/description and comments under it for budget friendly scanners for BMW VTG/transfer box reset: th-cam.com/video/eXYtgUqaSvI/w-d-xo.html

[@profsg]

​@@nevrcm3261no reset for differentials or even the transmission fluid change. Only for the transfer case.

[@claudiodecina2670]

Is it normal to feel a sort of "locked diff" feeling while turning at lower speeds?

[@fcpeuro]

😕

[@claudiodecina2670]

[@edgarhernandez8711]

@@fcpeurothat’s happens to me to can it be just the oil or internal damage?

[@claudiodecina2670]

@@edgarhernandez8711 okay will check it out, maybe needs fresh oil

[@soomz5159]

try flushing first... you may need to do 2-3 flushes (if not using a suction) with long drives in between. you'll want to drive it at least 100 miles after the flush and see if it improves. the transfer case issue seems to be noticeable at low speeds (figure 8s, parking lot speeds) and at high rpm/load scenarios. hopefully the transfer case just needs a flush and not a full replacement which is a lot of $.

Time to change the cheezy music now

😂 no man. We like it.

Music is fine
