Second Hand BMW Z4 Fuel Pump

Yes, every petrol BMW Z4 has a fuel pump – it sits in or near the fuel tank and feeds pressurised fuel to the injectors, so it is a genuine part you can source from a breaker. Diesel Z4s were never offered in the UK, so all UK-market Z4s are petrol and all have this component. If you have a petrol Z4 and the pump has failed, you are in the right place.

No – the E85/E86 roadster and coupe (2003–2009) and the second-generation E89 Z4 (2009–2016) are completely different platforms with different tanks, pump assemblies, and engine families, so the parts are not interchangeable. The current G29 Z4 (2018–present) is a third generation again, equally incompatible with either earlier car. Always buy within the same generation and, crucially, match the engine code from your V5 or a VIN check rather than just the year.

Engine code is the key detail here, because different engines run at different fuel pressures and use different pump specifications – a pump from a straight-six 3.0i is unlikely to be correct for a four-cylinder 2.0i even within the same generation. Give the breaker your exact engine code (found on your V5 or a VIN decoder) alongside your registration and they can confirm whether the donor pump matches your spec. Do not assume two Z4s from the same year are compatible just because they share a badge.

Possibly not – the sDrive20i uses a four-cylinder N20 engine while the sDrive28i also uses the N20 but at a different state of tune, and the sDrive35i uses a six-cylinder N54 or N52 engine, all of which may have different pump flow rates or assembly designs. Share your engine code with the breaker and ask them to cross-reference the part number against their donor vehicle's engine code rather than relying on the sDrive badge alone. Trim level and the sDrive designation make no difference to pump fitment – it is purely the engine that matters.

For the fuel pump itself, gearbox type does not generally affect the pump specification – the pump feeds the engine regardless of how the power is transmitted. That said, always confirm with the breaker against your registration, as there can be ancillary or mapping differences on some variants that could affect related components. The engine code remains the most important detail to supply.

No – M Sport, SE, and other trim designations on the Z4 are cosmetic and equipment packages; they do not change the engine or fuel delivery system. Two E89 Z4s with identical engine codes will use the same fuel pump regardless of which trim level they are. Focus on matching the engine code, and the trim badge can be safely ignored when sourcing this part from a breaker.
