BMW M4 Camshaft Replacement Parts

Yes, all BMW M4 variants across every generation are petrol-engined and use conventional piston engines with physical camshafts, so this is a genuine part on this model. The M4 uses BMW's DOHC (double overhead camshaft) architecture, meaning there are multiple camshafts per engine — intake and exhaust on each bank — so make sure you know which one you need (inlet or exhaust, and which cylinder bank) before requesting quotes. Supply your engine code to the breaker so they can pull the exact shaft required.

No — the F82 M4 (2014–2020) uses the S55 twin-turbocharged straight-six engine, while the G82 M4 (2021–present) uses the S58 twin-turbocharged straight-six, and these are entirely different engine families with different camshaft profiles and dimensions. Camshafts are engine-specific components, so parts do not cross between these two generations under any circumstances. Always quote your engine code (S55 or S58) to the breaker to ensure the correct part is sourced.

For most of the F82 generation, both the standard M4 and the M4 Competition share the S55 engine block and cylinder head architecture, so trim level alone does not typically determine camshaft compatibility. However, camshaft specifications can vary by engine code suffix and production date, so do not assume a standard-trim donor car's camshaft is identical to a Competition unit without confirming your exact engine code against the breaker's stock. Trim differences on the M4 are largely chassis tuning and interior — they do not change the fundamental engine components.

The F82 M4 ran from 2014 to 2020 with the S55 engine throughout, so a 2014 or 2015 car sits in the same generation as your 2017 car. In principle, camshafts from elsewhere in the F82 run share the same engine family, but ancillary specifications and any mid-production engineering changes are best confirmed with the breaker against your specific registration before buying. Providing your engine code from your V5 or a VIN check is the most reliable way to ensure a match.

No — body style has no bearing on camshaft fitment whatsoever, as the camshaft is determined entirely by the engine, not the body. The F82 (coupe) and F83 (convertible) M4 both used the same S55 engine, and the G82 (coupe) and G83 (convertible) M4 both use the S58 engine, so a camshaft from a convertible donor car is equally relevant to a coupe buyer within the same generation. Focus on the engine code and which specific camshaft position you need rather than the body style of the donor vehicle.

A camshaft is a mechanical component and does not carry any electronic pairing or immobiliser coding in the way that an ECU or instrument cluster might, so there is no coding concern with the part itself. However, if your camshaft replacement is being carried out alongside other work, or if ancillary sensors attached to the camshaft are being swapped, confirm with your fitting garage and the breaker whether any associated components require configuration. The key fitment risk with a used camshaft is mechanical compatibility via the engine code, not electronics.
