Used BMW 6 Series Fuel Tank

The modern BMW 6 Series runs across two main generations: the E63/E64 (2003–2010) and the F06/F12/F13 (2011–2018), with the F-series receiving a facelift around 2015. These generational boundaries matter because the fuel tank design changed between them, so an E-series tank will not fit an F-series car and vice versa. Always confirm your generation with the breaker using your registration or VIN before ordering.

Both 2014 and 2016 6 Series fall within the F06/F12/F13 generation (2011–2018), but 2014 sits before the 2015 facelift and 2016 sits after it, so there is a production boundary between them. The fuel tank itself may well be common across that facelift, but ancillary fittings and mounting points can change mid-production, so you should confirm compatibility with the breaker against your specific registration rather than assume it crosses cleanly.

Yes, fuel type is critical — a diesel 6 Series (for example, a 630d or 640d) will have a different tank configuration to a petrol model such as a 640i or 650i, and the two are not interchangeable. Beyond fuel type, the engine code is the most reliable guide, as it tells the breaker exactly which drivetrain variant your car runs; you can find this on your V5 or via a VIN check. Always give the breaker your engine code alongside your registration to get the right match.

Gearbox type is worth mentioning to the breaker because tank shape and sender unit positioning can vary between automatic and manual variants in some configurations. It is less critical than fuel type or engine code for the tank itself, but supplying your full spec — engine code, fuel type, and gearbox — gives the breaker everything they need to cross-reference accurately. Never assume a tank from a different gearbox variant will be a straight swap without the breaker confirming it.

Trim level does not affect fuel tank fitment on the BMW 6 Series; M Sport, SE, and other trim grades share the same mechanical underpinnings and the same tank for a given engine and generation. The differences between trims are cosmetic — suspension tuning, body styling, and interior equipment — none of which influences the fuel tank. Focus on matching engine code, fuel type, and generation rather than trim badge, and you will be sourcing the right part.

No — the E63/E64 and F12/F13 are entirely different generations with different floorpan architecture, so the fuel tanks are not interchangeable between them. Even within each generation, details such as sender unit connections and filler neck routing can vary by engine code and fuel type, so the generation boundary is only the first filter. Give your breaker your registration, VIN, and engine code so they can match the tank precisely to your car.
