Used BMW X6 Fuel Pump

Every BMW X6 has a fuel pump of some kind, but the type varies by engine: petrol engines use a high-pressure direct-injection pump as well as an in-tank low-pressure pump, while diesel engines use a separate high-pressure diesel injection pump alongside an in-tank lift pump. Because of this, you must match the replacement pump to the correct fuel type and engine code, not just the model year or badge. Quoting your engine code (found on your V5 or a VIN check) to the breaker will save a lot of back-and-forth.

Almost certainly not without significant work — the E71 is the first-generation X6 (2008–2014) and the F16 is the second generation (2014–2019), and these generations use entirely different engines, fuel systems, and mounting arrangements. Even where engine families look similar across the boundary, ancillary and mounting details can differ mid-production, so you should confirm compatibility with the breaker against your exact registration and engine code rather than assuming year overlap is enough. Sticking within the same generation is a much safer starting point.

Trim level itself does not affect fuel pump fitment — what matters is whether the engine code and fuel type match, not whether the car is a standard xDrive, an M Sport, or an M Performance variant. However, the M50d uses a different engine to the xDrive30d (three turbos versus two, different injection pressures), so the high-pressure pump is unlikely to be interchangeable even though both are diesel. Always cross-reference the engine code, not the trim badge.

This spans the E71-to-F16 generation change: the E71 ran until 2014 and the F16 launched in 2014, so a 2013 car is definitely E71 but a 2014 or 2015 car could be either generation depending on build date. If both cars share the same engine code you may have a better chance of compatibility within the same generation, but fitment across the E71/F16 boundary — and for any ancillary or mounting changes that occurred mid-production — is something you should confirm with the breaker against both registrations rather than assume.

Yes, fuel type is critical — a diesel high-pressure pump operates at completely different pressures and has a different physical design to a petrol direct-injection pump, and the two are not interchangeable. Even within petrol or diesel, different engine codes (for example N57 versus B57 diesel) can use different pump specifications, so fuel type narrows it down but the engine code is what really confirms the match. Give the breaker both your fuel type and your engine code for a reliable quote.

On some BMW fuel systems the high-pressure pump or its control circuitry can interact with the engine management system, and whether a used unit will work straight away or need any coding is something you should confirm with the breaker and your installer before buying. This is not something that can be stated as a blanket rule, as it can depend on the specific pump type and model year. A good breaker will be able to advise based on your registration, and your fitting garage should be aware of this before the job starts.
