Used BMW 7 Series Timing Chain

The BMW 7 Series has used timing chains across multiple generations — E38 (1994–2001), E65/E66 (2001–2008), F01/F02 (2008–2015, facelift 2012), and G11/G12 (2015–2022) — and the chain itself is determined almost entirely by engine code, not by which generation the car belongs to. Where the same engine code carried across a generation boundary, the chain may well be shared, but ancillary components like tensioners, guides, and sprockets can change mid-production without a badge change, so confirm the full engine code from your V5 or a VIN check and give it to the breaker before buying. Never assume a match based on year alone.

Yes, fuel type matters enormously here: the 730d is diesel and the 740i is petrol, and these engines are entirely different units with different timing chain configurations, so the parts are not interchangeable. Your engine code is the definitive guide — for example a B57 diesel and a B58 petrol share nothing in their valve-train assemblies. Always quote your engine code to the breaker rather than just the badge number.

No — SE, Sport, and M Sport are trim designations that affect interior specification, wheels, and bodykit, not the engine internals. Two 7 Series cars with identical engine codes will use the same timing chain regardless of trim level. Focus on confirming your engine code and fuel type, which are the details that actually determine the correct part.

The F01/F02 generation ran from 2008 to 2015 with a recognised facelift in 2012, and in most cases the engine codes carried across that facelift unchanged, meaning the timing chain itself was unaffected. However, ancillary components around the chain — tensioners, guides, and related hardware — can see running changes mid-production that don't align neatly with facelift years, so confirm any of those items against your registration with the breaker rather than relying on the facelift date alone.

The timing chain is driven by the engine and is unaffected by whether the car is rear-wheel-drive or xDrive four-wheel-drive — both layouts use the same engine unit. What matters is the engine code, which you can find on your V5 logbook or via a VIN check, and that is the detail to give your breaker when requesting a quote.

Yes — all BMW 7 Series variants across every generation have been chain-driven rather than belt-driven, so a timing chain exists on every engine variant the model has been sold with, from the early six-cylinder petrols and diesels in the E38 through to the modern turbocharged units in the G11/G12. However, many engines — particularly the N47 diesel used in this era across the BMW range — have a known reputation for chain wear, so when sourcing a used chain from a breaker it is worth asking about the mileage and condition of the donor vehicle. Always confirm the engine code to ensure you receive the correct chain assembly for your specific unit.
