I finally got around to changing the Tcase oil @~60,000km. I left the brace on. It was quite tight and I have fairly slim fingers.

I bought a 14mm Hex socket and hammered out the bit.
With a bit of fiddling and patience, I was able to get it through the gap to loosen the fill/drain plug. Then it was just a matter of ratcheting slowly.

Yes a small tube is recommended to suck out the original fluid.
I managed to remove abit over 350ml after all. Just like the diff oils, the fluid was dark.
I used the BMW branded Tcase (1000ml) oil. Ended up filling > 400ml. Going to keep the rest for future change..... years from now.

Key tools for the "brace-on" method:
- 14mm Hex bit
- 14mm box/open ratchet
- Mallet to knock the plug loose
- Small diameter tube
