To ensure the utmost care for your vehicle, it is essential to be informed about certain operational issues related to the drivetrain. Let's delve into three primary concerns associated with BMW cars featuring automatic transmission (AT) and xDrive.
Queries regarding BMW with AT and xDrive
1). Is it necessary to change the oil in the automatic transmission? If so, after how many kilometers?
2). Should the oil in the differentials be changed for xDrive? If yes, after how many kilometers? Additionally, how should one generally care for xDrive?
3). Do original TPMS sensors (equipped in the car from the dealership) have the ability to adapt to individual positions? Specifically — if the left wheel is moved to the right, will the readings be accurate? Will the car read the left wheel the same as the right?
The issue pertained to the BMW M135i xDrive model with automatic transmission, but it can be encountered in other models as well.
Answers
1). Yes, the oil in BMW with AT and xDrive should be changed every 60-70,000 km under normal operating conditions (mixed city/highway driving, no towing of trailers, no sporting goods). For the M series cars, with significantly increased power and torque, oil change intervals should be shorter.

2). Yes, the oil in the front and rear axles should be changed every 200,000 km, the oil in the VTG gearbox (xDrive) should be changed at least every 70,000 km. The general operating conditions for BMW with xDrive are the same as in the first point.
3). Pressure sensors in new BMW models are assigned to the wheel position in the car, any change in wheel position requires re-adaptation (assignment) of the sensor to the new position.
