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 Seri…
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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The B57 D30 C is generally robust with excellent refinement and strong performance. Early models (2019–2020) had a tendency for high-pressure fuel pump instability under sustained load, but the 2021 ECU update (SIB 11 55 21) significantly improved fuel delivery stability. When maintained properly—using correct oil (0W-30 LL-17) and following service intervals—these engines are durable and well-suited for executive and SUV applications.
The most documented issues are HPFP instability (pre-2021), DPF clogging from short trips, EGR valve carbon buildup, and turbo actuator sticking. These are covered in BMW service documentation. While not all units fail, awareness and proactive maintenance—especially ECU updates and highway driving—can prevent performance issues.
This 3.0L twin-turbo diesel engine was used in several BMW models: the G30 5 Series 530d, G11 7 Series 730d, G05 X5 xDrive30d, and G06 X6 xDrive30d (2019–2023). It is part of BMW's modular B-series engine family, offering high torque and smooth delivery in flagship applications.
Yes, the B57 D30 C responds well to ECU remapping. Stage 1 tunes typically yield +40–60 kW, leveraging the robust stock turbos and internals. Higher stages may require supporting mods like intercooler upgrades. Tuning is popular on 530d and X5 xDrive30d models. However, ensure cooling and fuel systems are in optimal condition before tuning to avoid heat-related issues.
In real-world driving, expect 6.8–8.2 L/100km (35–29 mpg UK) in mixed conditions. Highway efficiency improves to ~6.0 L/100km (~39 mpg UK), while aggressive driving can exceed 10.0 L/100km (23 mpg UK). The DPF and engine management help maintain efficiency, but optimal economy requires smooth driving habits and use of quality diesel.
Yes, the B57 D30 C is an interference engine. If the timing chain fails or jumps, piston-to-valve contact is likely, resulting in severe internal damage. While the chain is designed for the life of the engine, any unusual noises from the timing cover should be investigated immediately to prevent catastrophic failure.
BMW specifies 0W-30 synthetic oil meeting BMW Longlife-17 (LL-17 FE+) standard. This low-viscosity oil ensures rapid flow at startup and protects the timing chain and turbo bearings. Change intervals are typically 15,000 km or annually. Using non-compliant oil can accelerate wear and void warranty or service claims.
