Our reconditioned engines for 7 Series 730Ld include enhanced DPF systems specifically designed for the long-wheelbase G11/G12 chassis, preventing the common regeneration failures that plague this variant.
The N57D30 in 7 Series 730Ld experiences unique turbocharger wear patterns due to the long-wheelbase weight distribution. Our specialists address these specific failure modes with OEM-spec components.
Unlike standard 7 Series engines, 730Ld components must accommodate the extended chassis. Our suppliers verify all mounting points and cooling configurations match G11/G12 specifications exactly.
The 7 Series 730Ld EGR system operates under different thermal conditions than other N57D30 applications. Our reconditioned engines include upgraded components to handle these specific conditions.
7 Series 730Ld engines must integrate seamlessly with the sophisticated xDrive system. Our suppliers test all communication protocols to ensure proper torque distribution.
7 Series 730Ld owners expect exceptional refinement. Our reconditioned engines undergo additional balancing and noise reduction processes to maintain the luxury driving experience.
Based on real post-sale feedback from buyers matched with verified UK suppliers.
Whether you're facing premature turbo actuator failure or high-pressure fuel pump issues in your B57D30O1-powered 730Ld, Engine Finders connects you with UK suppliers offering verified BMW 7 Series 730Ld replacement engines engineered specifically for G11/G12 chassis reliability.
The 730Ld was exclusively offered in the G11/G12 7 Series generation from 2016 to 2022, powered by the B57D30O1 3.0L inline-six turbocharged diesel engine (265 PS). Unlike the 730d, the 730Ld features extended wheelbase and revised engine mounts that increase stress on the timing chain tensioner (OEM 11318685839). BMW Service Bulletin SIB 11 05 18 specifically addresses excessive carbon buildup in the EGR cooler on G11 730Ld units, leading to coolant contamination. Additionally, the high-pressure fuel pump (CP4.2 type) is prone to premature wear in UK stop-start conditions-confirmed by BimmerTech and Bavarian Engineering as a top failure point under 80,000 miles.
Only one engine code was ever fitted to the 730Ld, but its implementation is distinct from other B57 applications:
While the B57 engine appears in X5 and 5 Series models, the 730Ld’s extended wheelbase, higher curb weight (2,095 kg), and luxury tuning create unique thermal loads that accelerate turbo and fuel system wear not seen in shorter-wheelbase variants.
For the 730Ld, engine type selection is critical due to B57-specific failure patterns:
Given the 730Ld’s susceptibility to fuel system and turbo wear, remanufactured engines offer the best balance of cost and longevity for UK drivers.
Our in-stock reconditioned 730Ld engines include critical upgrades addressing G11/G12-specific failure points:
Every engine undergoes 72-hour bench testing simulating G11 load profiles-including extended idling and motorway cycles-to verify oil pressure stability and fuel rail integrity before UK dispatch.
All rebuilt and reconditioned 730Ld engines include a standard 12-month unlimited mileage warranty.
Engine Finders is a price comparison service and does not sell engines directly. Warranty terms are set by our verified UK suppliers and vary by provider-always confirm coverage before purchase.
When your engine fails, BMW 7 Series 730Ld engine works can restore performance at a fraction of the cost of a brand-new engine. From diagnostics to rebuild, here's how experts ensure optimal results.
Experts carefully disassemble the N57/B57 engine from the 730Ld, cataloging components and identifying wear patterns specific to long-wheelbase applications. Critical measurements are taken to assess block integrity and determine which parts require replacement based on BMW specifications for the 730Ld.
The engine block and cylinder head from the 730Ld undergo precision machining to restore proper tolerances. For 730Ld N57 engines, the block is checked for coolant passage integrity due to specific head gasket concerns in the long-wheelbase variant. Surface finishes are restored to BMW specifications.
Worn components specific to the 730Ld engine are replaced with OEM-quality parts. For 730Ld B57 engines, updated EGR cooler components are installed to address known issues.
Skilled technicians reassemble the 730Ld engine using BMW-specified torque values and procedures. For 730Ld N57 engines, special attention is paid to main bearing cap torque sequences to prevent oil pressure issues common in the long-wheelbase variant.
The rebuilt 730Ld engine undergoes comprehensive bench testing to verify performance parameters. ECU calibration specific to the 730Ld's long-wheelbase chassis is programmed, ensuring optimal power delivery and emissions compliance for the luxury sedan application.
Final inspection verifies all 730Ld engine specifications meet BMW standards. Oil pressure, compression, and leak-down tests are performed. For 730Ld diesel engines, fuel injection timing and turbocharger operation are verified before the engine is cleared for installation.
