When replacing power steering pump:
Fluid reservoir Service and Repair 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.
