This video shows how I serviced the transmission of this 2016 BMW X1 F48 xDrive25i.
The transmission is actually made by AISIN and is also used by Volvo as the TG81 8 speed gear box.
The fill plug O-ring part number is 24278627917, it is a T55 and torqued to 45nm.
The drain plug O-ring part number is 24278627913, it is a 17mm hex and torqued to 35nm.
The oil level setting plug O-ring part number is 24278627907, it is a T40 and torqued to 8nm.
the transmission fluid is BMW ATF 6 part number 83222355599.
You will need a scanner that can read the transmission oil temperature. It needs to be between 50 and 60 Celsius when setting the level.
