WARNING: This page does not describe the selected car, but rather 47 other vehicles, including the 2016 BMW M5, 2016 BMW ActiveHybrid 5, 2016 BMW 550i xDrive, 2016 BMW 550i, and 2016 BMW 535i xDrive. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: When replacing power steering pump:
OIL RESERVOIR must be replaced in event of metal abrasion, sluggish pump shaft or increased dirt contamination!
The filter integrated in the oil 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 oil reservoir as metallically glittering hydraulic fluid.
It is only necessary to replace the oil reservoir because of leaks (e.g. at hose connections) only in the event of the unavoidably high ingress of dirt.

WARNING: DANGER OF POISONING if oil is ingested/absorbed through the skin!
DANGER OF INJURY if oil comes into contact with eyes and skin!

WARNING: Adhere to the utmost cleanliness. Do not allow any dirt to enter the hydraulic system.
Do not draw off hydraulic fluid (risk of contamination).

Necessary preliminary work:

Lower FRONT AXLE SUPPORT .
Draw off and dispose of hydraulic fluid from oil reservoir.
Remove BELT PULLEY .
