Second Hand BMW M4 Fuel Pump

Yes, all BMW M4 variants are petrol-engined and use a high-pressure direct-injection fuel pump (and in many cases a low-pressure lift pump as well), so the fuel pump is a genuine fitment on this model. The M4 has never been offered in diesel, so there is no diesel pump variant to consider. If you have been quoted for a diesel fuel pump, double-check the part description with the breaker.

Both sit within the F82 generation (2014–2020) and share the S55 twin-turbocharged 3.0-litre straight-six engine code, which is the key fitment factor for the fuel pump. In principle the pump should carry across, but ancillary mounting or connector changes can occur mid-production without a formal facelift, so confirm the exact part number against your registration with the breaker before buying.

The F82 M4 (2014–2020) uses the S55 engine, while the G82 M4 (2021–present) uses the S58 engine — these are different units and their high-pressure fuel pumps are not the same part. You must source a pump matched to your engine code, not just the M4 badge. Always give the breaker your engine code from the V5 or a VIN check to make sure you receive the correct pump.

No — trim level does not affect fuel pump fitment on the M4. The Competition variant uses the same S55 (F82 generation) or S58 (G82 generation) engine as the standard M4, and the fuel pump follows the engine code, not the trim badge. The only differences between standard and Competition models relevant to a buyer are suspension, software, and interior items, none of which affect pump compatibility.

Gearbox type can be relevant for some fuel system components in certain applications, but on the M4 the high-pressure fuel pump is driven off the engine and is not directly tied to the gearbox type. That said, it is worth mentioning your gearbox to the breaker when requesting a quote, as they can cross-reference the full part number and rule out any minor ancillary differences. The engine code remains the most important detail to supply.

The single most useful piece of information is your engine code — S55 for the F82 generation (2014–2020) or S58 for the G82 generation (2021–present) — which you can find on your V5 logbook or via a VIN check. Also provide your registration, model year, and fuel type (all M4s are petrol) so the breaker can verify the exact part number. Whether the pump needs ECU pairing or immobiliser coding after fitting is something you should confirm directly with the breaker or a BMW specialist, as this varies and cannot be guaranteed in advance.
