Used BMW iX Cylinder Head

The BMW iX (U11) launched in the UK in 2022 and is still in its first generation, so there is no named facelift boundary to worry about yet — but engine specification changes can still occur within a production run, and the engine code is the only reliable way to confirm whether a donor head will match yours. Check your V5 or run a VIN check to get the exact engine code before approaching a breaker. Never assume a head fits based on year alone; always confirm against your registration with the breaker.

Both the 2022 and 2024 iX sit within the same first-generation U11 platform, so on the surface they look compatible — however, ancillary and mounting details can change mid-production without a formal facelift, which means a head that looks right on paper may not be a straightforward swap. Your engine code (found on the V5 or via a VIN check) is the single most useful detail you can give a breaker. Confirm fitment against your specific registration with the breaker before purchasing.

Yes — the xDrive40 and xDrive50 use different electric drive units and, critically, different motor configurations, so any internal components including cylinder heads are not interchangeable between them. The engine code stamped on your V5 or revealed by a VIN check will confirm exactly which unit your vehicle has. Always supply that code to the breaker rather than relying on the badge alone.

No — M Sport is a trim and styling package on the iX, not a separate mechanical specification, so it does not affect which cylinder head you need. What matters is the engine code, which will be identical across standard and M Sport variants sharing the same drivetrain. You can safely buy a head from any trim level provided the engine code matches yours, and you can ignore cosmetic differences between donor and recipient cars entirely.

This is a genuine concern on modern BMWs, and whether a used cylinder head requires ECU coding or immobiliser pairing when fitted to your specific iX is something you should confirm directly with the breaker against your registration — it is not something that can be stated as a blanket rule here. A good breaker who deals in BMW parts regularly will be able to advise on what programming work, if any, is likely to be needed. Factor potential coding costs into your budget before committing to a purchase.

The most important detail is your engine code, which you can find on your V5 logbook or by running a VIN check through a reputable online service — this matters far more than the year or trim of your car. You should also confirm your fuel type (the iX is fully electric, so if you are searching for a motor or drive unit component rather than a traditional cylinder head, make that clear to the breaker). Giving the breaker your full registration alongside the engine code will allow them to cross-reference and advise on any fitment concerns specific to your vehicle.
