Used BMW M5 Fuel Tank

The E60 M5 ran from 2005 to 2010 and all used the S85 V10 engine, so tanks from within that generation are your strongest starting point for a used match. That said, confirm with the breaker against your registration whether any ancillary or mounting changes occurred mid-production, as these can affect pipework and sender unit compatibility. Never assume fitment is guaranteed without that check.

The M5's S85 V10 has different fuelling demands and the tank, sender unit, and pump arrangements may not match those of the standard E60 petrol models, so a direct swap is unlikely to be straightforward. Engine code is the critical detail here — the M5 carries the S85 code whereas a 550i carries the N62, and these are fundamentally different cars mechanically. Ask your breaker to cross-reference your specific registration rather than relying on the shared E60 bodyshell.

These are two distinct generations — the F10 M5 ran from 2011 to 2016 and used the S63 twin-turbo V8, while the F90 M5 replaced it from 2018 onward with a developed version of the S63 in a new platform. Because the platforms and underbodies differ significantly, a tank from an F10 is very unlikely to suit an F90, and we'd route this firmly to a breaker to confirm against both registrations before ordering. Crossing a named generation boundary like this always needs verification.

The F10 M5 received a facelift in 2013, but the S63 engine code remained consistent throughout the generation from 2011 to 2016, which is a positive sign for tank compatibility. However, whether any mounting, pipework, or ancillary changes occurred around the 2013 facelift point is something you should confirm with the breaker against your specific registration, as mid-production changes to fuel system fittings can catch buyers out. The engine code match is encouraging, but it does not guarantee the ancillary details align.

For the F90 generation, the M5 Competition shares the same S63 engine code and platform as the standard M5, and trim level does not affect fuel tank fitment. The Competition designation reflects suspension, software, and cosmetic differences rather than any change to the fuel system or tank. You may find the donor car has different surrounding components or finishes, but the tank itself should not vary by trim — confirm the engine code and generation with your breaker and you are starting in the right place.

The single most useful detail is your engine code, which you can find on your V5C logbook or by running a VIN check — for example S85 for the E60 M5 or S63 for F10 and F90 cars. Also provide your registration, the generation of your car, and your fuel type, as these let the breaker cross-reference accurately rather than working from the badge alone. Gearbox type can also be worth mentioning as it occasionally influences fuel system layouts, and confirming any of this against your registration with the breaker is always the safest final step.
