This genuine BMW alternator pulley fits E70 X5 3.0si (2007-2010) and E71 X6 35i N54 (2008-2009)

This pulley is known as a overdriving, decoupling, OAD, or ADP pulley and has an internal dampening system that can wear out or fail. This can cause improper belt tension, vibration, slipping, noise, and poor alternator performance. There is no suggested replacement interval so check the overall condition of the pulley and listen for buzzing or squealing noises from the pulley itself. Removal and installation requires a special tool - see Related Items below.
