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 was engineered for refined driving dynamics and responsive performance in BMW's flagship lineup. Emissions compliance was achieved through exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, meeting Euro 5 standards across its production run. Its all-aluminum block and twin-scroll turbo layout provided smooth operation and high durability under sustained load.
One documented reliability concern is high-pressure fuel pump (HPFP) wear, particularly in early production units before 2012. This issue, referenced in BMW Service Information Bulletin 13 01 12, is attributed to internal cam follower wear under low lubricity fuel conditions. In 2012, BMW revised the HPFP internal components, improving longevity and reducing failure rates in later models.
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 single VGT turbo provides strong low-RPM torque ideal for highway cruising but requires adherence to 15,000 km oil change intervals to prevent high-pressure fuel pump wear. BMW Longlife-04 (5W-30) oil is essential due to its lubricity and thermal stability protecting the HPFP. Extended idling or use of low-sulfur diesel below EN 590 standards accelerates pump wear in pre-2012 engines. The Bosch CRS 2.0 system is robust but sensitive to fuel quality; always use ultra-low-sulfur diesel (ULSD). Post-2012 models feature revised HPFP internals per BMW SIB 13 01 12, significantly enhancing long-term reliability.
Oil Specs: Requires BMW Longlife-04 specification (BMW SIB 11 01 12). ACEA C3 compatible oils acceptable.
Emissions: Euro 5 certification applies to all models (2009–2015) (VCA Type Approval #VCA/EMS/5730).
Power Ratings: Measured under DIN 70020 standards. Output consistent across fuel qualities (BMW TIS Doc. A35100).

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.
Locate the engine code stamped vertically on the right-side engine block near the starter motor (BMW TIS A35200). The 7th VIN digit indicates engine family ('D' for N57 series). Pre-2012 models have silver valve covers with "N57" branding; post-2012 units use black valve covers with "N57" marking. Critical differentiation from N55: N57 D30 B is a diesel VGT inline-six; N55 is a petrol twin-turbo inline-six. Service parts require production date verification - fuel pumps for engines before 08/2012 are incompatible with later units due to internal redesign (BMW SIB 13 01 12).
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.
