The M57 (1998-2013) is the most reliable BMW diesel engine, followed by the modern B47 (2014-present). Avoid the N47 (2007-2014) due to timing chain failures unless replaced, and approach the N57 (2008-2020) with caution due to rear-mounted timing chain replacement costs exceeding £2,000.The M47 is an older-generation engine, simpler and more reliable, with a front-mounted timing chain. It is a great choice for those who value reliability and want to avoid costly repairs. The N47 is more dynamic, more fuel-efficient, and more modern, but unfortunately less reliable due to its rear-mounted timing chain.

Which is better, N57 or M57?
How does the M57 compare to the N57 engine? The M57 is simpler and more durable, while the N57 offers improved efficiency and slightly higher performance but can have electronic and timing guide issues. Most N57 variants employ a twin-turbo system, often a variable geometry turbocharger (VGT) paired with a smaller, quicker-spooling turbocharger. This sequential turbocharging setup ensures that there’s boost available across a wide range of engine speeds.
