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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

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.
Aftermarket ECU tuning is common on the B57D30C platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
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.
