Used BMW M3 Camshaft

Yes, every petrol engine in every generation of BMW M3 has camshafts – they are a fundamental part of any four-stroke internal combustion engine, controlling the opening and closing of the intake and exhaust valves. All M3 engines across every generation, from the original S14 four-cylinder through to the S58 twin-turbo straight-six, use conventional camshaft arrangements, typically with dual overhead camshafts (DOHC). There is no M3 variant that is diesel or electric, so there is no generation where a camshaft is absent.

Almost certainly not – the E36 M3 uses the S50 or S52 straight-six engine depending on market and year, while the E46 M3 uses the entirely different S54 straight-six, and these engines share no internal rotating components. Engine code is everything with camshafts, and these are different engine families with different bore spacing, valve timing specifications, and cam profiles. Always match the camshaft to the specific engine code shown on your V5 or a VIN check, and confirm the exact part number with the breaker before purchasing.

Yes – the saloon (E90), coupe (E92), and convertible (E93) M3 all share the same S65 4.0-litre V8 engine, so body style has no bearing on camshaft fitment whatsoever. The S65 has a DOHC layout per cylinder bank, giving it four camshafts in total, and these are common across all three bodystyles of that generation. Confirm the engine code from your V5 or a VIN check and supply it to the breaker, as that is the detail that matters.

Trim level does not affect camshaft fitment – both the standard F80 M3 and the M3 Competition use the same S55 3.0-litre twin-turbo straight-six engine, so the camshafts are drawn from the same engine family. The Competition pack primarily alters suspension tuning, software, and minor cosmetic details, none of which touch the valvetrain. Supply your engine code and registration to the breaker to confirm the exact specification, as there can be ancillary or minor component changes within a production run that are worth verifying.

This is very unlikely – the G80 M3 uses the S58 engine while the F80 M3 uses the S55, and although both are BMW twin-turbo straight-sixes they are distinct engine generations with different internal architecture and cam specifications. Camshafts are precision-ground components specific to their engine block and head design, so cross-generation fitting between different engine codes is not a safe assumption. Confirm the engine code from your V5 or VIN check and put the question directly to the breaker, who can check part numbers against both applications.

A camshaft itself is a purely mechanical rotating component and does not carry any electronic coding, so it does not pair to the ECU or immobiliser the way some other components do. However, the S55 engine in your F80 uses VANOS variable valve timing, and any sensors or actuators associated with the camshaft position should be confirmed with the breaker as to whether they are included and compatible with your vehicle. It is always worth confirming ancillary details against your registration with the breaker before you buy, as mid-production specification changes can occasionally affect associated hardware.
