32 41 037 Removing and installing power steering pump for power steering gear with Dynamic Drive (N54)

WARNING: This page is about a different car, the 2010 BMW 535i, 2009 BMW 535i, and 2008 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: Danger to life!
SECURE ENGINE IN INSTALLATION POSITION to prevent it from falling down.

IMPORTANT: Adhere to the utmost cleanliness. Do not allow any dirt to enter the hydraulic system.
Seal off hydraulic lines with plugs.

NOTE:

When replacing power steering pump:

FLUID RESERVOIR must be replaced in event of metal abrasion, sluggish pump shaft or increased wear!

The filter integrated in the fluid reservoir can only absorb a limited amount of foreign particles. If the filter clogs, the hydraulic system can no longer be sufficiently protected.

Metal abrasion is perceived in the fluid reservoir as metallically glittering hydraulic fluid.

It is only necessary to replace the fluid reservoir because of leaks (e.g. at hose connections) only in the event of the unavoidably high ingress of dirt.

Necessary preliminary tasks:

Draw off and dispose of hydraulic fluid from fluid reservoir
Remove BELT PULLEY
Lower FRONT AXLE CARRIER
