XDrive Transfer Case Fluid DIY

I don't see any reason why you couldn't re-use a coper
sealing washer. You could flip it over if you wanted-to if you're worried about it sealing correctly in its current state of deformation.

Looks like the dealers should sell the washers for ~50p based on RealOEM.

What's the Romanian scanner gizmo?

I'm looking to sell the car soon and buy an E70 so wondering whether this is worth doing or leave for the next owner to do on it's next service. I don't have any negative symptoms just put the scanner on because of a fuel injection error which looks like a clogged fuel filter based on the facts that it only comes up under heavy acceleration and I recently got very very low on fuel so most of the crud from the bottom of the tank is now probably in the filter (put 92lt in to the 90lt tank on filling up after 615 miles).

Looks good. I won't be able to get to this for a few weeks, I don't have the parts or the GT1 head yet. Can you update on how you get along with it? Really interested to know if it's simple for you to do the sensor reset tool yourself using this tool.

Do you check transfer case fluid level hot or cold? Or doesn't matter?

I don't know the official procedure, but I would check it cold. There isn't enough fluid in there for thermal expansion to be an issue.

Thanks. Just received the X-Drive transfer case fluid kit from ECS Tuning. I going to tackle this today.

Procedure is cold. There really isn't even a full can of it in there. Adaptations can be reset with INPA or DIS. Get the Romanian cable software deal on ebay. Worth the $15 it costs, all you need is a win xp laptop.

I didnt reset my adaptations for a while. I forgot how long. Nothing bad happened. When i did reset them, it seemed smoother, but that could be a placebo effect.

The old oil looked almost new (still light brown). Maybe I didn't need to change... But good to know it has fresh new oil in there. I have Scanner 1.4 but didn't see anywhere to reset transfer case so adaptation is not reset. Not sure if adaptation process is a must procedure. Everything feels good and smooth as before. Thanks, I'll look for different software package with more functionality so I can reset transfer case for piece of mind.

THANKS for the great instructions, changed mine today.

Read that bolts get stuck -easy to strip, lots of the "kits" come with new bolts. Mine came off very easy, sprayed them with penetrating oil an hour before. I bought new crush washers but would not have hesitated to reuse the old. The proper torque of 33nm didn't seem tight enough or my torque is off - although I am defiantly an "over tighten". I used a scrap piece of pipe to slip over the wrench and act as an extension breaker bar on the drain side (you can't get a socket in).

I prefer to shimmy under the car rather then use ramps and jacks, couldn't do that with this one as your breaker bar or socket handle hits the ground.

I took the BMW bottle of fluid to AUTOZONE to get a pump. The guy there asked how much I paid for the "BMW" fluid and laughed when I said about $40. He showed me there equivalent and said it meets all standards and costs about $20.

I shook the bottle to mix the additives? read that in this thread.

I only have INPA and very confused by it, read different opinions on if INPA can clear the adaptation value??
