This part is listed by BMW as BMW part number 11282413245 (11 28 2 413 245) and is described as a factory overhaul kit for the vibration damper (11238511371), main belt tensioner (11287799851), deflection pulley (11287799859), and main drive belt (11288477787) on the M57 Diesel engine found in E70 X5 35d.
Note: there appears to be two different styles of deflection pulley on the M57. This version uses a short 35mm mounting bolt with an Allen head. The other uses a very long 170mm mounting bolt and has a external Torx head. The belt and tensioner are the same.
This is a Genuine BMW belt and pulley service kit with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
