XDrive Transfer Case Fluid DIY

[lhordmclain]

Awesome update!
We have the same year/model/color
But I only have 90k+ miles.

A bit dirty X5 - On the road now going back to Windy City ( visited Mt Rushmore & Crazy horse with the family)

I never bothered to reset the adaptation values so I think I've proved you can safely skip that step if you prefer. I now have 170,000 miles on my 2004 E53 X5 3.0 and it is still going strong. I just ordered one liter of Xdrive fluid and I will be doing my second fluid change within a couple of weeks. I will take a shot of the old fluid again and post for all to see.

I changed my Xdrive fluid for the second time at 180k miles tonight. I had planned to do it every 50k or so but never found the time. I was surprised to see the fluid in better shape this time after the same 90k interval. Still dirty but only about 60% as black as the first change at 90k. I did not reset the adaptation values the first time and had no trouble so I didn't bother with it this time either.

Thanks for the update!

Changed an F25's fluids today: transfer case (was black), front diff (was clear), gearbox (dark, some 'dust' on the magnets), left the rear diff as the front was so clear (and had some doubts to how to do it right). And the fuel filter was done. First time i saw a dealer-serviced car that actually had a fuel filter with a date on it later than first delivery...

Also changed the 'driver' of the rear led lights (the ones in the tailgate) as one side did not light up any more.


Also done the engine oil (what a construction that 2.0 diesel engine: air filter 'hat', oil filter in the back, oil filling with a spill catcher that leads to a hidden place under that 'hat'. While there is lots of room to work at the front (as 2 - 4 cylinders are missing).


What a pile of screws after removing all the plastic and metal covers!



Unfortunately ran out of time for the transfer case and gearbox reset. However, there were no issues before, it was all done at approx 150000km (not miles) for the first time.



Next week my E70 (2007) is up. Same list of stuff to do, this one at 180000km and 4 cylinders more. Curious to see the state of the various liquids as this one has more years and lots more torque than the F25.

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.

Did this ever fix your "vibration when exiting a turn" issue?
