BMW 5 Series Cylinder Head Replacement Parts

The BMW 5 Series has run through several well-established generations: E34 (1988–1996), E39 (1996–2003), E60/E61 (2003–2010), F10/F11 (2010–2017, facelift 2013), and G30/G31 (2017–2024). Cylinder heads follow the engine code rather than the generation badge, so heads from different generations can sometimes share the same engine family, but crossing a generation boundary — for example from an E60 into an F10 — brings real risks around ancillary and mounting changes that are hard to confirm without checking your specific registration against the breaker's donor car. Always give the breaker your full engine code from your V5 or a VIN check before agreeing a purchase.

Both the 520d and 525d use diesel engines from the same BMW N47 or B47 family depending on year, but the displacement and tune differences mean the engine codes are not always identical, so the heads are not automatically interchangeable. The engine code is the single most reliable guide here — it sits on your V5 or can be confirmed through a VIN check — and you should quote it directly to the breaker rather than relying on the badge alone. Never assume fitment based on the model number suffix.

No — SE, Sport, M Sport, and xDrive trim levels on the BMW 5 Series are cosmetic and specification packages that do not change the cylinder head required. What matters is the engine code, fuel type, and the generation of the car, all of which remain the same regardless of whether the donor or recipient car wore an M Sport badge or an SE badge. You may find cosmetic differences between stripped donor cars from different trim levels, but mechanically the head itself is unaffected by trim.

The F10/F11 generation ran from 2010 to 2017 with a facelift introduced in 2013, and while the engine codes across that range are often shared, there can be ancillary and mounting changes introduced at or around the facelift that affect how a head fits or what additional components you need. The safest approach is to confirm with the breaker that their donor car's engine code matches yours exactly, and give them your registration so they can cross-reference the full spec. Naming the facelift boundary is useful context, but whether a specific head crosses it safely is something to verify with the breaker rather than assume.

Quote the full engine code — N57 in your case — along with your vehicle's registration, the variant suffix if you know it (for example N57D30A or N57D30B, as these denote different outputs and can affect head specification), and whether your car is a manual or automatic. The breaker can then check the donor vehicle's code against yours and confirm whether any ancillary items such as sensors or valvetrain components need to transfer across. Giving the engine code directly is far more useful than quoting the model year or badge, and it is the single detail most likely to get you a compatible part.

No — petrol and diesel cylinder heads are completely different in design, combustion chamber shape, and porting, and they are not interchangeable under any circumstances. Always make clear to the breaker whether your engine is petrol or diesel before they quote, and back that up with your engine code, which will confirm the fuel type unambiguously. Mixing fuel types is not a fitment grey area — it is a hard incompatibility.
