The BMW B57 D30 C is a 2,993 cc, inline-six turbocharged diesel engine produced from 2019 to 2023. Part of BMW's modular B-series engine family, it features a twin-turbo setup (sequential low- and high-pressure turbos), common-rail direct injection, and advanced thermal management. Delivering 210 kW (286 PS) and 650 Nm of torque from 1,750 rpm, this engine is engineered for high-performance luxury and SUV applications.
Installed in flagship models such as the G11 7 Series, G30 5 Series, and G05 X5, the B57 D30 C emphasizes smooth power delivery, refinement, and towing capability. It meets stringent Euro 6d-ISC-FCM emissions standards thanks to its diesel particulate filter (DPF), selective catalytic reduction (SCR) with AdBlue injection, and dual-loop exhaust gas recirculation (EGR) system. The engine is longitudinally mounted and features an integrated starter-generator (ISG) in mild-hybrid variants.
In 2021, BMW issued Technical Service Bulletin 11 55 21 addressing early reports of high-pressure fuel pump (HPFP) rail pressure instability. The update included revised fuel pump calibration and updated injector control logic to improve delivery consistency. This change reduced instances of hesitation and improved long-term injector health, particularly under high-load conditions.
All production years 2019–2023 meet Euro 6d-ISC-FCM standards (VCA UK Type Approval #VCA/EMS/9013).
The BMW B57 D30 C is a 2,993 cc inline-six twin-turbo diesel engine engineered for executive and SUV models (2019–2023). It combines sequential turbocharging with common-rail injection to deliver strong low-end torque and linear power delivery. Designed to meet Euro 6d-ISC-FCM, it balances performance with emissions compliance.

The sequential twin-turbo setup provides seamless boost delivery but requires strict adherence to 15,000 km oil change intervals using BMW Longlife-17 0W-30 to protect turbo bearings and the timing chain. The diesel particulate filter (DPF) requires regular highway runs for passive regeneration; frequent short trips increase clogging risk. The high-pressure fuel pump is sensitive to fuel quality; use of ultra-low-sulfur diesel (EN 590) is essential. Post-2021 models feature updated fuel control logic; pre-2021 units should follow BMW SIB 11 55 21 for calibration updates to improve injector longevity.
Oil Specs: Requires BMW Longlife-17 (LL-17 FE+) 0W-30 specification (BMW SIB 11 55 21). Supersedes LL-04 for diesel engines.
Emissions: Euro 6d-ISC-FCM certification applies to all models (2019–2023) (VCA Type Approval #VCA/EMS/9013).
Power Ratings: Measured under SAE J1349 standards. Full output requires EN 590 ultra-low sulfur diesel (BMW TIS Doc. A32005).

The BMW B57 D30 C was used across BMW's G11/G30/G05 platforms with longitudinal mounting. This engine received platform-specific adaptations-cooling system tuning in the G11 7 Series and transmission calibration in the G05 X5-and from 2021 received updated high-pressure fuel pump control logic to improve fuel delivery stability, creating minor service part and software differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front-facing side of the cylinder block, near the oil filter housing (BMW TIS A32020). The 7th VIN digit indicates engine family ('B' for B-series). Pre-2021 models have a silver high-pressure fuel pump housing; post-2021 units use updated ECU calibration (ZP21.04.10 or later) to improve fuel delivery stability. Critical differentiation from B57D30A: B57 D30 C features revised fuel control logic and updated injector mapping. Service parts require production date verification—fuel pumps and injectors for pre-2021 models may benefit from updated calibration per BMW SIB 11 55 21.
The B57 D30 C's primary reliability concern is high-pressure fuel pump instability in early builds, particularly in vehicles used for sustained high-load driving such as towing. Internal BMW field reports from 2022 indicated a rise in hesitation complaints below 100,000 km in pre-update units, while UK DVSA data shows low rates of emissions failures due to effective DPF and SCR management. Extended highway driving and inadequate maintenance increase fuel system stress, making ECU updates and service adherence critical for long-term performance.
