The BMW N57 D30 B is a 2,993 cc, turbocharged inline — six diesel engine produced between 2009 and 2015. It features DOHC, 24 — valve configuration with common rail direct injection, a variable geometry turbocharger (VGT), and double — VANOS variable valve timing. Rated at 180 kW (245 PS) and 540 Nm of torque, this engine delivers strong low — end pulling power ideal for executive and performance applications.
Fitted primarily to the F01 7 Series and F10 5 Series, the N57 D30 B wa…
Production years 2009–2015 meet Euro 5 emissions standards (VCA UK Type Approval #VCA/EMS/5730).
The BMW N57 D30 B is a 2,993 cc inline-six turbo-diesel engineered for executive sedans (2009–2015). It combines common-rail injection with a single variable-geometry turbocharger to deliver strong low-RPM torque and refined cruising. Designed to meet Euro 5 standards, it balances performance with improved fuel economy over its predecessor.

The BMW N57 D30 B was used across BMW's F01/F10 platforms with longitudinal mounting and no licensed external applications. This engine received platform-specific adaptations-revised cooling routing in the F01 and shorter accessory drives in the F10-and from 2013 the facelifted F10 LCI adopted the N57TU variant with revised EGR system and updated turbocharger, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The N57 D30 B's primary reliability risk is high-pressure fuel pump wear in early builds, with elevated incidence in high-mileage vehicles. Internal BMW quality reports from 2012 noted a significant share of pre-2012 engines requiring HPFP replacement before 180,000 km, while UK DVSA records show low emissions-related failures due to robust EGR and catalyst design. Extended oil intervals and poor fuel quality increase pump stress, making fuel and oil quality critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The N57 D30 B is generally robust, but early models (2009–2012) are prone to high-pressure fuel pump wear. Later revisions (post-2012) with improved HPFP internals significantly enhance longevity. Regular oil changes with BMW Longlife-04 spec oil and using high-quality diesel (EN 590) help prevent premature wear. Well-maintained engines often exceed 250,000 km.
Key issues include high-pressure fuel pump wear (pre-2012), EGR valve coking, turbo actuator sticking, and valve cover oil leaks. These are documented in BMW service bulletins and confirmed by long-term owner data. The HPFP issue is particularly common due to fuel quality sensitivity in early units.
The N57 D30 B was used in the F01 7 Series (730d) and F10 5 Series (530d) from 2009 to 2013. It replaced the M57D30 in certain applications and was later superseded by the N57TU with updated EGR and turbo. All applications meet Euro 5 emissions standards.
Yes. The N57 platform is highly tunable. ECU remaps can safely achieve 300-320 PS with stock components. Upgraded turbos, intercoolers, and fuel systems allow further gains. The inline-six block and crankshaft handle increased torque well, but HPFP condition must be verified first, especially in pre-2012 engines.
In a 730d (F01), combined consumption is ~6.8 L/100km (~41 mpg UK). Highway driving yields ~5.8 L/100km (~49 mpg UK), while city use can reach 8.5 L/100km (~33 mpg UK). Real-world figures depend on driving style, but the engine is efficient for a 3.0L diesel of its era.
No. The N57 D30 B uses a non-interference design. If the timing chain fails, pistons will not contact valves, preventing catastrophic internal damage. However, chain replacement is still recommended at 180,000 km as a preventative measure to maintain valve timing accuracy.
BMW specifies 5W-30 oil meeting BMW Longlife-04 spec. Use high-quality synthetic oil and change every 15,000 km or annually. Proper oil selection is critical to protect the high-pressure fuel pump, especially in pre-2012 engines. Avoid low-detergent or non-synthetic oils.
