32 41 037 Removing And Installing/Replacing Power Steering Pump For Power Steering Gear With Dynamic Drive (S63)
WARNING: This page is about a different car, the 2013 BMW X5, 2012 BMW X5, and 2011 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.
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.
