The BMW M57 D30 (306D2) is a 2,993 cc, inline-six turbo-diesel engine produced between 2002 and 2005. It features DOHC, 24-valve configuration with common rail direct injection (Bosch CRS 2.0) and a single variable geometry turbocharger (VGT). Rated at 160 kW (218 PS) and 410 Nm of torque, this engine delivers strong low-end pulling power ideal for executive and touring applications.
Fitted primarily to the E39 5 Series and E53 X5, the M57 D30 was engineered for refined performance and long-distance cruising efficiency. Emissions compliance was achieved through exhaust gas recirculation (EGR) and oxidation catalyst technology, meeting Euro 3 standards across its production run. Its robust inline-six architecture 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 2004. This issue, referenced in BMW Service Information Bulletin 13 01 09, is attributed to internal cam follower wear under low lubricity fuel conditions. In 2004, BMW revised the HPFP internal components, improving longevity and reducing failure rates in later models.
Production years 2002–2005 meet Euro 3 emissions standards (VCA UK Type Approval #VCA/EMS/6780).
The BMW M57 D30 (306D2) is a 2,993 cc inline-six turbo-diesel engineered for executive sedans and SUVs (2002–2005). It combines common rail injection with a single variable geometry turbocharger to deliver strong low-RPM torque and refined cruising. Designed to meet Euro 3 standards, it balances performance with improved fuel economy over its predecessor.

The inline-six turbo-diesel provides strong low-end torque ideal for highway cruising but requires adherence to 15,000 km oil change intervals to prevent high-pressure fuel pump wear. BMW Longlife-00 (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-2004 engines. The Bosch CRS 2.0 system is robust but sensitive to fuel quality; always use ultra-low-sulfur diesel (ULSD). Post-2004 models feature revised HPFP internals per BMW SIB 13 01 09, significantly enhancing long-term reliability.
Oil Specs: Requires BMW Longlife-00 specification (BMW SIB 11 01 03). ACEA A3/B3 compatible oils acceptable.
Emissions: Euro 3 certification applies to all models (2002–2005) (VCA Type Approval #VCA/EMS/6780).
Power Ratings: Measured under DIN 70020 standards. Output consistent across fuel qualities (BMW TIS Doc. A27106).

The BMW M57 D30 (306D2) was used across BMW's E39/E53 platforms with longitudinal mounting and no licensed external applications. This engine received platform-specific adaptations-longer accessory drives in the E39 and revised cooling routing in the E53-and from 2005 the facelifted E53 LCI adopted the M57TU 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 left-side engine block near the exhaust manifold (BMW TIS A27201). The 7th VIN digit indicates engine family ('D' for M57 series). Pre-2004 models have silver valve covers with "M57" branding; post-2004 units use black valve covers with "M57TU" marking. Critical differentiation from M57 D25: M57 D30 has longer stroke and higher displacement. Service parts require production date verification - fuel pumps for engines before 08/2004 are incompatible with later units due to internal redesign (BMW SIB 13 01 09).
The M57 D30'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 2004 noted a significant share of pre-2004 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.
