XDrive Transfer Case Fluid DIY
You'll need the following: 1 quart BMW XDrive transfer case fluid Part #83220397244 2 new copper sealing rings Fluid pump Lift/jack/jack stands Ratchet wrench/breaker bar 16mm socket 16mm spanner Torque wrench Oil catch ******************** First, buy yourself some XDrive fluid. I bought mine at ECS Tuning - $45 per quart - OUCH! Luckily, you only need one. Next, get your ride up in the air. I bought a MaxJax lift last year and love it. That being said, I always have backup support in the form of at least two tall jack stands under the lift arms. Better safe than sorry. Remove the 16mm fill plug near the top of the transfer case (large bolt in upper center of photo) on the front side of the vehicle. A socket will fit here. It's a little tough so you may need a breaker bar to make it easier: Next position your oil catch under the drain plug and remove the drain plug. You can't get a socket on the 16mm drain plug (large bolt on bottom far right in photo) because it's too close to the subframe support member. You will have to use spanner/open end wrench. Because of this, you can't get a breaker bar on it so you're going to have to muscle it off: After the fluid has drained replace the old copper ring with a new one and reinsert the drain plug. Because I couldn't get a socket on the plug I couldn't use my torque wrench so I had to torque it the old fashioned way; I tightened good and snug and hoped for the best. If you can somehow get a torque wrench in there, the proper torque is 33nm (24 lb-ft). Next, attach your fluid pump to the XDrive fluid bottle (it takes a large mouth type pump). Pump the fluid into the fill hole until it just runs over. Replace the copper ring and reinsert the fill plug. The proper torque is again 33nm (24 lb-ft). Clean up and take it for a test drive. You're done! Here's what the old vs. new fluid looked like after 91,500 miles: Last edited by texmln; 07-17-2017 at 09:36 PM. Reason: Photobucket dicks! |

There's one step left. Adaptation values should be reseted after fluid change. As far as I understand you can only do it with coding tools.

Does 01' has xDrive? If not, is there any similar fluid that I need to change on my 01' 3.0i? Differential Fluid?

No it doesn't i believe it comes around 2004 but may be wrong.

Agreed; the transfer case fluid seems to be the most dirty. I recommend it as part of Inspection II (that's when I had it done).

sethro - no change in the feel, which I generally take to be a good thing.
chris - I believe the adaptation values only need to be cleared when replacing the entire transfer case, not for fluid changes. The transfer case is responsible for calculating the following factors: Condition of transfer case fluid Clutch plate wear Servo load Fluid temperature |

Good to know I'm planning on doing this soon

I just changed mine because my tech read the value which stated that the oil was ready to be changed. He said a sensor measures the resistance of the oil to determine when it needs changed, but it doesn't clear when you put in new oil. He also said most dealerships don't check that computer at inspections unless you ask. I watched him reset the value after I changed it.
