July 13 - Jan 14 F15 X5s may have faulty drive gears - SI B33 01 14

F30 3 series produced with fault final drive

If your F15 X5 was produced between July 2013 and January 2014 have it checked out by the dealer soon! BMW has issues a service bulletin (SI B33 01 14) for incorrectly produced final drive gears. The gears are mounted in the differential and transfers the engine power 90 degrees from the transmission to the wheels. In the affected vehicles the final drive gears were not properly hardened. Improperly hardened final drive gears could break under heavy acceleration resulting in possible wheel lock up and loss of vehicle control.

Affected models produced between July 2013 and January 2015
  • F15 - X5 SAV
  • F30 - 3 Series Sedan
  • F31 - 3 Series Sport Wagon
  • F32 - 4 Series Coupe
  • F33 - 4 Series Convertible
  • F34 - 3 Series Gran Turismo

So I was told by the stealership that I need to pay $100 to have any service bulletin looked at and that it's only performed under warranty if the vehicle develops an issue. Is this actually how it works at every dealer?

Any input is appreciated.

Thank You
