Cheap BMW 4 Series Throttle Body

Most BMW 4 Series engines are turbocharged petrol or diesel units, and turbocharged BMW engines generally use a different air management approach to traditional throttle bodies — many use a throttle valve integrated within the intake manifold or turbo system rather than a conventional standalone throttle body as found on older naturally aspirated engines. Whether a discrete, replaceable throttle body exists on your specific engine depends heavily on the engine code, so check your V5 or run a VIN check to get the exact engine code before searching. Confirm with the breaker whether a serviceable throttle body unit is available for your specific engine code, as they will be able to cross-reference this against your registration.

The F32-generation 4 Series ran from 2013 to 2020, with a facelift in 2017, so a 2014 car and a 2017 car sit either side of that facelift boundary. Engine codes are the critical factor here — if both cars share the same engine code (for example both being N20, B48, or whichever unit applies), the underlying engine architecture may be compatible, but ancillary and mounting changes can occur mid-production around a facelift. Confirm with the breaker against your registration whether the specific throttle valve or intake component from the earlier car crosses that 2017 boundary for your engine code.

Yes — for any mechanical intake component on a BMW, the engine code is the single most important detail, outweighing the model year or even the generation. Two 4 Series cars from the same year can have completely different engine families (for example N20 versus B58), and parts from one will not suit the other. Pull the engine code from your V5 logbook or a VIN check and give it to the breaker so they can match the part accurately.

The badge reflects engine displacement and tune, but the engine code is what actually determines which throttle valve or intake component fits — a 430i and a 440i use different engine families (B48 versus B58 respectively in later F32 production) and would need different parts. The body style — whether you have a coupe, convertible, or Gran Coupe — makes no difference whatsoever to intake components like this. Give the breaker your engine code rather than just the badge number and they will be able to confirm whether a listed part suits your car.

No — trim levels like SE, Sport, M Sport, and M Sport Plus are cosmetic and equipment packages; they do not change the engine internals or air intake components. A throttle body or throttle valve unit is determined entirely by the engine code and fuel type, not by whether the car has M Sport bumpers or upgraded seats. Buy on engine code, not on trim badge.

Diesel engines, including the common BMW 4 Series diesels such as those with N47 or B47 engine codes, do have a throttle or swirl flap valve in the intake tract, but this is a different component to a petrol throttle body and serves a different function — it is typically used to aid engine shutdown or control exhaust gas recirculation. If you are looking for this part on a diesel, describe it to the breaker as a swirl valve or intake flap rather than a throttle body, and give them your exact engine code and registration so they can identify the correct component for your car.
