This part is listed by BMW as BMW part number 32411094098 (32 41 1 094 098) and is described as Power Steering Pump for the 1997-1998 528i (E39 chassis).
The first two years of the E39 528i used the M52 (single vanos) 2.8 liter straight 6 cylinder engine. This was the power steering pump used on these two model years of 528i.
Not for 528i after the 1998 model year. After 1998, BMW changed the engine, so any 528i after the 1998 model year will need the later style PS pump (and not this one).
While you may find less expensive power steering pumps for the early (97-98) 528i sedan, we can only recommend an OEM Luk for quality, performance, longevity and overall value. This is the pump we use when a new PS pump is needed on any BimmerWorld shop-serviced 528i models, or employee owned cars.
