Cheap BMW 1 Series Fuel Injector

The BMW 1 Series F20/F21 ran from 2011 to 2019, with a facelift in 2015, so a 2012 car is pre-facelift and a 2015 car sits right at that boundary. The engine code is the critical factor here — if both cars share the same engine code (for example N20B20 or N47D20), there is a reasonable chance the injectors are the same, but mid-production and facelift changes can affect ancillary specifications. Confirm the engine codes from both V5s or a VIN check, then verify directly with the breaker that the part suits your exact registration before buying.

The E87 generation ran from 2004 to 2011 and the F20/F21 generation ran from 2011 to 2019 — these are entirely different platforms with different engine families, so injectors are very unlikely to be interchangeable. Even where a similar engine code exists across generations, the fuel system specification, injector connector, and flow rate can differ. Always supply both engine codes to the breaker and confirm fitment against your specific registration.

Yes, absolutely — petrol and diesel engines use fundamentally different injector types, and diesel direct-injection systems (such as those on N47 engines) operate at far higher pressures than petrol port or direct-injection systems (such as those on N43 or N20 engines), making them completely incompatible. Within petrol variants, port-injected and direct-injected engines also use different injector designs, so the engine code is essential. Check your V5 for the engine code and confirm with the breaker that the injector matches your exact engine before purchasing.

No — trim level does not affect injector fitment at all on the BMW 1 Series; SE, Sport, M Sport, and M140i trims with the same engine code use the same injectors. What matters is the engine code, not the badge or interior specification. Give the breaker your engine code and registration, and the trim name can be ignored for this purpose.

The 116d used the N47D20 diesel engine across much of the F20 generation, and injectors for that engine code are what you need — not simply any part labelled 116d, as production changes over the model's run (2011–2019) mean specifications can vary. Supply your full engine code (visible on the V5 or through a VIN check) to the breaker, as this is more reliable than the 116d badge alone. Confirm fitment against your registration directly with the breaker, particularly if your car is from the later part of the production run.

Gearbox type does not affect injector fitment — the injectors are part of the engine's fuel system and are identical regardless of whether the car has a manual or automatic gearbox, provided the engine code is the same. The engine code is what the breaker needs from you, not the gearbox specification. Confirm the engine code from your V5 and verify with the breaker before purchasing.
