Thanks for the write up. I am about to do the same for my 2017 X3 (xDrive N20) and I have the following two question:
(1) Anyone has the torque spec for the supporting bracket fastener. I thin the drain/fill plugs should be torqued at 60nm. but I don't have those for the supporting bracket.
(2) I am still very confused of which oil used in the transfer. My Toyota truck use 75w90 for transfer. but X3 uses transmission oil in transfer case? Make it worse - The FCP Euro suggest to use BMW DTF1 (part#: 83222409710); however the ECS Tuning says "does not fit". So which fluid is right for the transfer case?
