Cheap BMW 6 Series Air Flow Meter

Yes, but only on petrol-engined variants — the air flow meter (also called a mass air flow sensor or MAF sensor) is fitted to the petrol engines in the 6 Series lineup, such as the 630i, 640i, and the V8-powered 650i. The diesel engines in the 6 Series (630d, 640d) use a different air management strategy and do not use a conventional air flow meter in the same way, so if you have a diesel 6 Series you are likely looking for a different part — confirm with the breaker what your engine actually requires. Always quote your engine code when searching.

These are two entirely separate generations — the E63/E64 ran from 2003 to 2010 and the F12/F13 from 2011 to 2018 — and the engines, engine management systems, and MAF sensor designs are fundamentally different between them, so parts do not cross over. Your engine code is the key detail here: an E63 630i and an F12 640i use different engines and will need different sensors. Do not assume fitment across this generation boundary — confirm with the breaker against your registration.

Both fall within the F12/F13 generation (2011–2018), and where the engine code is the same the MAF sensor is generally the same part, but there were running production changes during this generation's lifespan that can affect ancillary components and sensor specifications. Confirm with the breaker against your exact registration and engine code before buying, as mid-production changes are something the breaker can verify against your VIN.

No — trim level does not affect air flow meter fitment at all, as this is a mechanical engine component determined entirely by the engine fitted, not by whether the car is an SE, Sport, or M Sport. The one important exception is the M6, which uses the high-performance S63 V8 engine rather than the standard N63, so an M6 air flow meter is not interchangeable with a standard 650i unit despite both being V8 petrol cars. Always match on engine code regardless of trim badge.

Body style makes no difference to air flow meter fitment — the MAF sensor is determined by the engine code, not by whether your car is a coupe (F12), convertible (F12 cabriolet), or Gran Coupe (F06). A 640i in any of those body styles with the same engine code will use the same air flow meter. Quote your engine code to the breaker and body style can be safely ignored for this part.

In most cases a replacement MAF sensor is a straight swap and does not require coding to the vehicle, unlike some other BMW electronic components. However, whether the replacement unit will work correctly with your car's ECU without any additional steps is something you should confirm with the breaker or a BMW specialist against your specific registration, as this can vary by engine and model year and is not something we can guarantee.
