Second Hand BMW 6 Series Power Steering Pump

It depends on the generation. The E63/E64 6 Series (2003–2010) used a hydraulic power steering system and does have a conventional power steering pump. The F06/F12/F13 6 Series (2011–2018) switched to electric power steering (EPS), meaning there is no hydraulic pump on those cars at all. If you have an F-series 6 Series and are chasing a steering fault, you will be looking at an electric power steering rack or column unit, not a pump.

Only the E63 coupe and E64 convertible (2003–2010) have a hydraulic power steering pump. Within that generation, the pump is fitted across the engine range — whether you have a 630i, 645Ci, 650i, or the M6 — though the exact pump spec can vary with engine size, so always confirm the part number against your registration with the breaker. The later F06 Gran Coupe, F12 convertible, and F13 coupe (2011 onwards) have no pump to source.

The E63 ran from 2003 to 2010 as a single generation with a mid-life facelift around 2007, so a 2005 and a 2008 car sit either side of that facelift point. The core hydraulic system did not fundamentally change at the facelift, but whether the pump itself is a straight swap across that boundary is something you should confirm with the breaker against both registrations before buying. Engine size is the more important variable — a 630i pump and a 650i pump may not be interchangeable — so give the breaker your exact engine as well as the year.

No — trim level does not affect the power steering pump fitment on the E63. Whether your car is a standard 6 Series or the full M6, the pump is determined by the engine variant and model year, not by interior or exterior specification. The M6 uses a different engine (the S85 V10) so its pump will differ from the standard petrol cars, but that is an engine difference rather than a trim one. Tell the breaker your engine code and year and trim level need not come into it.

No. The 640i is an F-series 6 Series, which uses fully electric power steering with no hydraulic pump anywhere in the system. If you are experiencing heavy or faulty steering, the component you need will be part of the electric steering rack or column assembly, not a pump. A good breaker who specialises in BMW will be able to point you to the correct electric steering part once you give them your registration.

In most cases the body style does not affect the power steering pump itself, as the hydraulic system is driven by the engine rather than being specific to the roof structure. However, the engine fitted and the model year are the key matching points, and both coupe and convertible versions shared the same engine range across the 2003–2010 production run. Confirm the part number with the breaker using your full registration to be certain, as minor running changes can occur within a generation.
