Second Hand BMW X7 Camshaft

Yes, every BMW X7 has camshafts — all variants, whether petrol or diesel, use internal combustion engines with conventional valvetrain arrangements, so camshafts are present on all of them. The X7 has never been offered as a pure electric vehicle in the UK, so there is no variant where the camshaft is absent. What does vary significantly is the camshaft design, quantity, and specification depending on which engine is fitted.

The engine code is the single most important detail — it tells a breaker exactly which camshaft specification your engine needs, far more reliably than the badge or model year alone. You'll find the engine code on your V5C or via a VIN check, and it's worth supplying this to any breaker you contact. Fuel type (petrol or diesel) and the specific displacement (e.g. 3.0-litre inline-six versus 4.4-litre V8) also matter because camshaft profiles differ between these engines.

The BMW X7 G07 launched in 2019 and received a significant facelift in 2022, and while some engine codes carried across that boundary, camshaft interchangeability cannot be assumed without checking engine codes against each other. If both vehicles share the same engine code, fitment is much more likely, but ancillary or internal changes mid-production mean you should confirm this directly with the breaker against your specific registration before purchasing.

Trim level itself does not affect camshaft fitment — what matters is the engine code underneath the bonnet. However, the xDrive40i uses a B58 inline-six engine and the M50i uses the S63 twin-turbo V8, so these will have entirely different camshafts simply because they are different engines, not because of the trim designation. Always lead with the engine code when sourcing from a breaker rather than the trim name.

The camshaft itself is internal to the engine and is not directly affected by gearbox type, so the gearbox specification alone won't change which camshaft you need. That said, gearbox type can be a useful cross-reference to help a breaker identify the correct donor vehicle and confirm other details match. The engine code remains the primary factor, with fuel type and year as supporting details.

If the X5, X6, or X7 in question share the same engine code — for example both running a B57 diesel inline-six — the camshaft may well be the same part, and many breakers hold engines from across the BMW G-platform range. However, you should confirm the engine code match explicitly with the breaker rather than assuming model-to-model compatibility, as spec variations and running changes can create differences even within the same engine family.
