Transfer Case Servo Motor Repair Kit — BMW E60 / E90 ATC300 | OEM 27107546671
Fix xDrive Faults on Your BMW E60 or E90 — Rebuild the ATC300 Servo, Not Replace It.
The ATC300 transfer case servo motor is the actuator that controls AWD torque split on BMW E60 and E90 xDrive models. When it fails, you get xDrive fault codes, warning lights, and loss of 4WD function. A new unit costs $200–$400+. This kit rebuilds the original servo — replacing the internal gears and wear parts.
Why Rebuild vs. Replace
- Targeted Fix: Gears and wear parts are what fail — the housing and motor winding are almost always fine.
- Restores xDrive Function: Correct servo operation clears fault codes and restores full AWD engagement.
- Major Savings: OEM ATC300 servos cost $200–$400+. This kit does the job for $41.
