Original BMW M11 x 99 Torx Screw, Belt Tensioner Mount, E70 BMW X5 3.0si and xDrive30i (2007–2010)

This Original BMW Torx screw bolts the drive belt tensioner to the engine in the E70 BMW X5 3.0si and xDrive30i built for the 2007–2010 model years. BMW sizes it as M11 x 99, with an AL suffix on the size designation, and each bolt weighs 27 grams. BMW's parts data ties this number to the X5 3.0si with the N52N engine, with production starting in October 2006. The bolt is made in Germany and supplied as a genuine BMW part, so the head, length, and thread match what came on the car from the factory. At 29.95 it is a small part.

Original BMW Parts carry a 24-month parts warranty.

A belt tensioner keeps steady pressure on the accessory drive belt, and its mounting bolt holds the tensioner body fixed to the engine while the spring-loaded arm moves. BMW lists this Torx screw under its own part number for the X5 tensioner. This number is specific to the N52N X5 in BMW's parts data, so it should not be treated as an interchangeable screw for other BMW belt drives or for later X5 engines. It is sold individually, one bolt per order quantity.

Common Questions

Will this bolt fit an X5 with the V8 engine?
BMW's parts data shows this number for the N52N-powered X5 3.0si only, so V8 models are not covered.

Is this the same bolt BMW installed at the factory?
Yes, it is the genuine BMW Torx screw for the tensioner position, made in Germany.
