BMW 7 Series Air Flow Meter Replacement Parts

Yes, but only on petrol-engined variants — the air flow meter (also called a mass air flow sensor or MAF sensor) measures incoming air for the engine management system on petrol engines. Diesel 7 Series models (such as those with the 'd' suffix in the engine code, like the 730d or 740d) do not use an air flow meter in the same way and instead rely on a different type of boost and air management system. When searching, confirm whether your 7 Series is petrol or diesel, as quoting the wrong fuel type will result in an incompatible part.

The E38 (1994–2001) and E65 (2001–2008) are completely different generations with different petrol engine families, so the air flow meters are not interchangeable — the E38 used earlier M60, M62, and M73 petrol engines while the E65 introduced the N62 V8 and N73 V12 among others. The correct part is determined by the engine code, not the generation badge, so you need to match on engine code first and foremost. Supply your engine code (found on your V5 or via a VIN check) to the breaker so they can confirm the right meter for your specific engine.

No — trim level has no bearing on which air flow meter fits your 7 Series; SE, M Sport, and any other trim designation on the same engine code will all use the same air flow meter. The part follows the engine, not the badge or trim pack, so as long as the engine code matches between donor and recipient vehicle, the trim level of either car is irrelevant. Focus on supplying the engine code and fuel type to the breaker rather than the trim name.

The F01 7 Series ran from 2008 to 2015, with a facelift in 2012, so both a 2010 and a 2014 740i fall within the same generation — however, the N54 and N55 petrol engines used across this period are not identical, and ancillary sensor specifications can vary even within the same generation. Whether an air flow meter from a 2010 car crosses the 2012 facelift boundary safely is something to confirm with the breaker against both registration numbers, as minor running changes can affect sensor specification. Always give the breaker the full engine code from both vehicles rather than relying on the model year alone.

The G11/G12 generation runs from 2015 onwards, and across that range there are multiple petrol engine variants including the B48 four-cylinder and B58 six-cylinder units, each requiring a specific air flow meter. The single most useful piece of information you can give a breaker is the full engine code, which you can find on your V5 logbook or by running a VIN check — quoting just '730i' or '740i' is not enough as the same badge has covered different engine variants over the years. Providing your registration to the breaker allows them to cross-reference the exact spec and confirm fitment before you commit.

No — air flow meters are matched to the specific engine they serve, and a V8 unit (such as one from an N62 or N73 engine) will have different flow characteristics and connector specifications compared to a straight-six unit such as an N52 or N54. Fitting a meter from a different engine family will result in incorrect fuelling and likely engine management faults. Always match the air flow meter to the exact engine code of your vehicle, and confirm this with the breaker before purchasing.
