xDrive Transfer Case Fluid Service - BMW (M-Models)

SKU: EAS.000000
$225.00
Description

The transfer case is a critical component of the BMW xDrive all-wheel drive system, responsible for distributing power between the front and rear axles. Over time, the transfer case fluid degrades from heat, friction, and normal drivetrain wear. Regular fluid service helps maintain smooth operation, proper torque distribution, and long-term reliability.

Our BMW Transfer Case Fluid Service replaces the old fluid with high-quality OEM-approved fluid specifically designed for the advanced AWD system. 

Service Includes

  • Drain and replace transfer case fluid
  • Refill with BMW-approved transfer case fluid
  • Inspect transfer case housing and seals for leaks
  • Verify proper fluid level and operation
  • Reset applicable drivetrain adaptations (if required)

Why Transfer Case Service Matters

  • Maintains proper lubrication of internal clutches and gears
  • Ensures smooth torque distribution between front and rear axles
  • Reduces wear on AWD components
  • Helps prevent drivetrain binding or premature transfer case failure
  • Recommended Service Interval

While BMW may list the fluid as “lifetime,” we recommend servicing the transfer case every 30,000–50,000 miles, especially for vehicles that experience:

  • Spirited or aggressive driving
  • Track use
  • High-performance modifications
  • Frequent launches or hard acceleration

Routine maintenance helps protect the complex AWD system and avoid costly drivetrain repairs. Service applies only to xDrive models equipped with BMW’s AWD transfer case. Fluid type and capacity vary depending on drivetrain configuration
