Transfer Case Motor, URO - E84 X1, E70 X5, E71 X6

This part is listed by BMW as BMW part number 27107568267 and is described as URO Parts Set Positioning Motor or Longitudinal Torque Module (better known as a transfer case actuator motor) for E84 X1 28iX, E70 X5 35iX/50iX, and E71 X6 35iX/50iX.

This is the servo motor which engages the xDrive AWD (All wheel drive) system's transfer case. When it fails, the xDrive system will struggle or completely fail to engage. Faults and codes are recorded, and you may hear metallic crunching/grinding noises from the teeth of the gears not making proper contact and failing to engage the rack within the transfer case.

This part is a fairly common failure on the xDrive models.

This part is manufactured by an aftermarket supplier of European auto parts, including many driveline components. While not carrying OEM status, this part follows the design of the original very closely and uses similar materials. An aftermarket part may even have the same TUV approval as its OEM counterpart. The brand may even be OEM to another manufacturer besides BMW. This aftermarket brand has a two year warranty - the same as Genuine BMW and OEM brands.
