Second Hand BMW M4 Throttle Body

Yes, all BMW M4 generations are petrol-engined and use an electronically controlled throttle body as part of their engine management system, so this is a genuine part on the car. The F82 M4 (2014–2020) uses the S55 twin-turbocharged inline-six, and the G82 M4 (2021–present) uses the S58 twin-turbocharged inline-six, and each engine has its own throttle body design. If you are unsure which engine your car has, check your V5 or run a VIN check to confirm the engine code before sourcing a part.

Both a 2016 and a 2019 M4 fall within the F82 generation (2014–2020), both using the S55 engine, so the core throttle body specification should be the same. However, there were mid-production running changes across the F82 lifespan, so confirm with the breaker that the part number matches your registration before buying. Throttle bodies on modern BMWs may also require coding to the vehicle's ECU, so check with your garage or the breaker whether any adaptation work is needed after fitting.

No — the F82 M4 uses the S55 engine and the G82 M4 uses the S58 engine, and these are distinct units with different throttle body designs that are not interchangeable. The 2021 G82 generation is a clean-sheet engine in a new bodyshell, so parts from the outgoing generation should not be assumed to cross over. Always source a throttle body matched to your specific engine code, which you can confirm from your V5 or a VIN check.

On the F82 generation, the Competition Pack is a trim and chassis upgrade rather than a different engine — both standard and Competition models use the S55 engine, so the throttle body specification is the same. On the G82 generation, the M4 Competition again shares the S58 engine with the standard M4, so trim level alone does not change the throttle body. Where fitment is concerned, focus on the engine code rather than the Competition badge.

The M4 xDrive and the standard rear-wheel-drive M4 both use the S58 engine, so the throttle body is not affected by the drivetrain configuration. xDrive adds four-wheel-drive hardware beneath the car but does not alter the engine specification. Source by engine code (S58) and confirm the part number with the breaker against your registration to be sure.

This is a real consideration on modern BMWs — the ECU may need to relearn or the throttle body may require adaptation using BMW diagnostic software after fitting, and some units can be paired to the original vehicle's management system. Whether your specific unit requires coding is something to confirm with the breaker and your fitting garage before you buy, as it affects both cost and ease of fitment. Findapart's breakers can often advise based on the part and your registration, so raise it when you request your quote.
