Welcome to the Autorooto Freak channel. Greetings to all viewers, subscribers, supporters. So, to the point, the BMW B-57 is a 3.0 L inline 6 turbocharged diesel engine that is part of BMW's modular engine family, which also includes the 3-cylinder B37 and 4-cylinder B47 diesels, as well as the B-38, B-48, and B-58 petrol engines. Introduced in 2015, the B-57 replaced the highly regarded N57 diesel engine, aiming to further improve performance, efficiency, and reliability, particularly addressing some of the timing chain concerns of its predecessors. It is widely considered one of BMW's most successful diesel power plants. Review and opinions. The B-57 engine consistently receives glowing reviews from owners and automotive journalists. It is praised for its silky smooth operation, impressive power delivery, and remarkable fuel efficiency for a 3.0 L inline 6. Many consider it to be one of the best diesel engines on the market. Owners often highlight its effortless torque, making acceleration feel strong across the rev range, whether in sedans, SUVs, or even performanceoriented and performance models. Its refinement is a significant improvement over previous generations with a more modern and quieter sound. Reliability is also frequently cited as a strong point with many engines easily surpassing 300,000 km, 186,000 mi with proper maintenance. Advantages: Exceptional performance. The B-57 offers substantial power and torque, delivering strong acceleration and effortless cruising. Power outputs vary widely from around 195 kW 261 horsepower to 294 kW 394 horsepower in the quad turbo versions with immense torque figures up to 760nm 561 lbfd. Outstanding fuel efficiency despite its power. The B-57 is remarkably economical. Real world fuel consumption often falls between 5.5 and 7.5 L per 100 kilometers, 31 to 43 m per gallon US, or 38 to 51 mp gallon UK, depending on the vehicle and driving style. Some owners report even better figures on long highway drives. High refinement. Being an inline 6, it inherently runs smoothly. The B-57 is known for its quiet operation and lack of vibrations, contributing significantly to driving comfort, robust reliability. BMW has incorporated improvements in design and materials, making the B-57 generally very durable. Issues like timing chain stretch, which plagued some earlier diesels, are exceedingly rare in the B-57. Tuning potential. The robust construction of the B-57 means it has significant tuning potential with ECU remaps commonly adding 40 to 80 horsepower and 70 to 120 new m of torque without major mechanical modifications. emissions technology equipped with advanced emissions control systems including common rail injection up to 2500 bar and selective catalytic reduction SCR with AdBlue ensuring compliance with strict Euro6 standards. Lightweight construction. The engine features lightweight aluminum construction contributing to better fuel economy and handling. Disadvantages: Complexity of modern diesel systems. While improved, the DPF, EGR, and SCR, AdBlue systems are still complex and can be prone to issues if the car is predominantly used for short city drives or if maintenance is neglected. AdBlue sensor failure can occur, for example, which is a notable repair cost. potential for costly repairs if issues arise. Although rare from major mechanical failures, if a complex component like a turbocharger, especially in multi-turbo versions, or the high-pressure fuel pump fails, repair costs can be substantial. Weight. While lightweight for an inline 6, it's still a heavier engine than its four cylinder counterparts, which can subtly impact front-end dynamics in some smaller vehicles. Faults and breakdowns. The B-57 is one of BMW's more reliable diesel engines, but no engine is entirely fault-free. Potential issues, particularly at higher mileages, include EGR cooler failure. This is a known issue across various modern BMW diesels, including the B-57. The EGR cooler can develop leaks, leading to coolant loss and potentially engine overheating. BMW has issued recalls for EGR cooler replacements due to fire risks. Turbocharger wastegate issues. Some owners have reported rattling noises from the turbocharger wastegate actuator, particularly at low speeds or deceleration. If left unressed, this can affect boost pressure and performance. High-pressure fuel pump HBFB failure. While less common than in some older generations, HPFB failures can still occur, leading to long cranking times, loss of power, or the engine entering limb mode. Fuel quality is a factor. DPF clogging. Like all diesels with DPFs, frequent shore journeys without sufficient time for regeneration can lead to filter clogging resulting in reduced performance and DPF warning lights. Adlue system issues. Failures of the AdBlue injector or knock sensors can occur, leading to warning messages and potentially limiting engine power if not resolved. Swirl flap issues. Some E57 variants may still have swirl flaps in the intake manifold. While less problematic than in older engines, carbon buildup can affect their function or in rare cases lead to breakage. Oil leaks. General oil leaks from gaskets, eg valve cover, oil filter housing, are possible over time, as with any engine. Fuel consumption. The B-57's fuel efficiency is a standout feature. Real world consumption typically ranges combined cycle WLTP from approximately 5.5 L per 100 kilome for milder tunes like the 30D up to 7.5 L per 100 km for powerful quad turbo and performance versions. This translates to around 31 to 43 m per gallon US or 38 to 51 mp gallon UK. Highway driving. The B-57 truly shines on longer journeys with many owners reporting figures in the low 5 L per 100 kilometers of range. Over 45 m per gallon US/55 mp gallon UK and some even achieving 4.7 L per 100 km 60 m per gallon UK and lighter models. Timing. The BMW B-57 engine uses a timing chain strategically located at the rear of the engine gearbox side. Unlike some earlier BMW diesel engines, eg N47, the timing chain in the B-57 is notably robust and reliable with issues like chain stretch and guide failures being exceedingly rare. BMW has designed it as a lifetime component, and it generally lives up to that claim with proper maintenance. While there are anecdotal mentions of preventative replacements for extreme peace of mind, it is not a widespread common issue that warrants routine scheduled replacement like a timing belt. Oil for the B-57 engine. BMW recommends using BMW longlift 04 LL04 approved engine oil. Common viscosities include 0W30 and 5W30. Some variants might also use LL 12 FE fuel economy oil. Always confirm the specific recommendation for your vehicle from the owner's manual. Capacity. The oil capacity is typically around 6.5 L, but this can vary slightly depending on the specific model and variant, eg single, twin, or quad turbo. Change intervals. While BMW's recommended service intervals can be extended, eg 20,000 to 30,000 km or 12,000 to 18,000 mi, many specialists and proactive owners advocate for shorter intervals, such as every 10,000 to 15,000 km, 6,000 to 9,000 mi, especially if the car is driven hard or frequently in stopand go traffic. Using highquality fully synthetic oil that meets the BMW LL 04 specification is crucial for engine longevity and the health of the DPF and turbochargers versions and history.
