BMW 7 Series 730Ld Engines for Sale | Engine Finders

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.

BMW 7 Series 730Ld Replacement Engines

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.

BMW 7 Series 730Ld Models - Engines Codes

Only one engine code was ever fitted to the 730Ld, but its implementation is distinct from other B57 applications:

  • B57D30O1: 3.0L turbocharged diesel (265 PS) for 730Ld (G11/G12, 2016-2022). Features unique EGR calibration and reinforced timing chain tensioner. Known for CP4.2 high-pressure fuel pump failure and turbo actuator rattle after 75,000 miles.
  • B57D30O1 (Euro 6d-Temp): From late 2018, includes SCR and AdBlue system. Dosing valve (OEM 11618685912) failure is common in high-mileage 730Ld units due to UK short-trip driving.
  • B57D30O1 (Post-2020): Updated oil pump gears (OEM 11418685877) to address low oil pressure during cold starts-a known weakness in early G11 engines per SIB 11 05 18.
  • B57D30O1 (Revised Crankcase Ventilation): From 2019, includes updated PCV system to mitigate oil dilution in extended urban driving cycles specific to UK 730Ld usage patterns.

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.

Buy Used and Second-Hand BMW 7 Series 730Ld Engines

For the 730Ld, engine type selection is critical due to B57-specific failure patterns:

  • Used: Mileage-verified units with compression reports; suitable for short-term use but carry inherent CP4.2 pump risks.
  • Reconditioned: Includes replacement of turbo actuator and EGR cooler per SIB 11 05 18 guidelines.
  • Rebuilt: Fully disassembled with new high-pressure fuel pump and updated oil pump assembly.
  • Remanufactured: Factory-equivalent rebuild with all B57D30O1 updates-recommended for long-term G11/G12 reliability.

Given the 730Ld’s susceptibility to fuel system and turbo wear, remanufactured engines offer the best balance of cost and longevity for UK drivers.

BMW 7 Series 730Ld Engines in Stock

Our in-stock reconditioned 730Ld engines include critical upgrades addressing G11/G12-specific failure points:

  • New CP4.2 high-pressure fuel pump (OEM 13518685922)
  • Revised turbocharger actuator (OEM 11618685912)
  • Updated timing chain tensioner (OEM 11318685839)
  • Sealed EGR cooler assembly compliant with SIB 11 05 18

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.

Warranty for Replacement BMW 7 Series 730Ld Engines

All rebuilt and reconditioned 730Ld engines include a standard 12-month unlimited mileage warranty.

  • Covers turbocharger, fuel pump, and timing system failures
  • Excludes damage from pre-existing AdBlue or DPF faults
  • NB: B57D30O1 engines installed in G11 chassis prior to 2019 have limited coverage on high-pressure fuel pumps due to known CP4.2 design limitations

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.
