Intended Use and Fitment for BMW 3 Series

The presented power steering pump is dedicated to BMW 3 Series models of the E90, E91, and E92 generations after the facelift (LCI) with the N47N engine. Its placement in the front – right side zone means it is structurally prepared to work with the factory engine accessories and hydraulic lines in these body versions.

Its placement on the right front side of the vehicle facilitates servicing and diagnostics, and also minimizes the need for modifications during replacement. The original body geometry allows for correct pulley alignment and proper drive belt tension.
