Second Hand BMW X4 Camshaft

Every BMW X4 has camshafts regardless of engine — petrol or diesel, four-cylinder or six-cylinder, all internal combustion engines use camshafts to operate the valves. The X4 has never been offered as a pure electric vehicle, so there are no variants where the camshaft is absent. What does vary significantly is the design and specification of the camshaft, which is determined almost entirely by which engine is fitted.

The engine code is the single most important piece of information — more so than the year, badge, or trim level, because BMW fits several different engines across the X4 range and camshaft profiles differ between them. You'll find the engine code on your V5C or via a VIN check, and sharing it with the breaker will allow them to match the part accurately. Fuel type (petrol or diesel) and gearbox type are also relevant secondary checks worth confirming.

The F26 is the first-generation X4 produced from 2014 to 2018, while the G02 is the second-generation model launched in 2018 and still in production — these are entirely different platforms with different engine families, so a camshaft will not simply swap between them. Even where a similar engine displacement appears in both generations, the engine codes are typically distinct and the camshaft specifications differ. Always confirm with the breaker against your exact registration and engine code before purchasing.

Yes, it matters a great deal — each of those badges indicates a different engine, and each engine has its own specific camshaft design, lobe profiles, and dimensions. The xDrive20d, xDrive30d, and M40d are all diesel but with different engine codes, different power outputs, and in some cases different numbers of camshafts. Always supply your engine code to the breaker rather than relying on the badge alone, as the engine code is the definitive reference for matching this part.

No, trim level does not affect camshaft fitment at all — xLine, M Sport, and M40i refer to styling and equipment packages, not mechanical differences in the engine internals (except where the badge also denotes a genuinely different engine, as with the M40i or M40d which have distinct engine codes). What matters is the engine code, which you should confirm via your V5C or a VIN check and share with the breaker. Expect cosmetic differences between trim-level donor cars at the breaker, but the camshaft itself is an engine component and trim has no bearing on it.

The changeover from the F26 to the G02 X4 happened during 2018, so a 2018 car could be either generation depending on the month of manufacture. This distinction is critical for camshaft fitment because the two generations use different engine families with different engine codes. Check your V5C or run a VIN check to confirm your engine code, then provide this to the breaker so they can match the correct part to your specific vehicle.
