Used BMW 6 Series Water Pump

Yes, all BMW 6 Series variants have a water pump as part of their cooling system — this applies across the E63/E64 (2003–2010), F06/F12/F13 (2011–2018), and G32 Gran Turismo generations, covering petrol and diesel engines alike. Whether driven mechanically off the engine or electrically (as on some later units), the water pump is a genuine fitment on every variant of this model.

Both years fall within the E63/E64 generation (2003–2010), so fitment is plausible, but the critical factor is the engine code — a pump from the same engine code is the right starting point, as even within a generation BMW used different units across the N52, N62, and M57 engine families. Confirm the engine codes of both donor and recipient vehicles match before buying, and check with the breaker against your registration to rule out any mid-production ancillary changes.

Yes, engine code is the single most important factor — petrol and diesel variants use entirely different water pumps, and even within petrol models the N52 straight-six and N62 V8 in the E63/E64 generation, or the N55 and N63 turbocharged units in the F12/F13 generation, each use distinct cooling components. Always check your engine code, which you can find on your V5 or via a VIN check, and supply it to the breaker when requesting a quote.

The F12/F13 generation ran from 2011 to 2018 with a facelift in 2015, and water pump fitment is primarily driven by the engine code rather than the facelift year. If the engine code is identical across both cars, fitment is likely, but you should confirm with the breaker against your registration as ancillary mounting or specification changes can occur across a production update.

No, trim level does not affect water pump fitment — SE, Sport, and M Sport are cosmetic and equipment distinctions that have no bearing on the engine's cooling system. What matters is the engine code, which can be the same across multiple trim levels; just confirm the engine code matches and let the breaker verify compatibility against your registration.

The 640d uses a diesel engine (N57 family in the F12/F13 generation), and a used pump from another 640d with the same engine code is a sensible match to look for. However, even within what appears to be the same engine, specification details can vary by year, so always confirm the exact engine code with the breaker against your registration rather than relying on the badge alone.
