Several refills of the PS pump will essentially provide a system flush. Usual method is to disconnect the low-pressure hose and attach a piece of tubing to extend this hose to a collection pan. Also plug the exposed fitting on the pump reservoir. Remove the pump drive belt and manually turn the pump until the reservoir is almost empty; then refill the reservoir with new fluid. Do this several times, using at least a quart of fluid. Reconnect the return hose and top off the reservoir. The pump can be driven with an air wrench or drill motor. Operating the pump with the car's engine, however, will probably evacuate the system much too quickly and run the pump dry. Use the proper type of fluid when refilling. See the attached link for other tips from a BMW site---similiar procedures. Eautorepair.net has online access to service manuals for a fee.....should have the factory procedure in them.
