The BMW N47 is a 2.0-liter turbocharged diesel inline-four produced from 2007 to 2015, serving as the workhorse of BMW's compact and midsize diesel range across Europe and other non-US markets. Combining common-rail direct injection with a variable-geometry turbocharger, the N47 delivered a compelling blend of low-end torque and impressive fuel economy that made it one of the most widely fitted engines in BMW's diesel history.
Engineering & Specs
The N47 replaced the older M47 and introduced a more modern, compact architecture. Depending on tune and turbocharging arrangement, it produced between 141 and 204 horsepower and a stout 258 to 280 lb-ft of torque, with a diesel-appropriate 5,000 rpm redline. Higher-output variants used sequential twin-turbocharging to broaden the powerband and eliminate low-rpm lag.

Which BMWs Used It
The N47 saw extensive service across BMW's diesel model lineup, most notably in the 118d through 125d range and the internationally popular 320d. These applications made it a familiar sight in European driveways, where diesel efficiency was prized for daily commuting and long-distance touring alike.

Reliability & Ownership Notes
As a high-volume diesel, the N47 rewards diligent maintenance. Enthusiasts should prioritize:
- Timing chain health: The N47's rear-mounted timing chain is well known among owners, so listen for rattle at startup and keep to strict oil-change intervals.
- Fresh oil and quality diesel: Clean lubrication protects the turbo and injection system.
- DPF and EGR care: Regular highway driving helps keep the diesel particulate filter regenerating properly.
A well-documented service history is the single most important factor when shopping for an N47-powered BMW. Address any timing chain concerns proactively rather than deferring them.
Legacy
The N47 cemented BMW's reputation for building diesels that were both economical and genuinely enjoyable to drive, thanks to abundant torque low in the rev range. While its four cylinders sit at the efficient end of BMW's engine family, they share the brand's engineering pedigree with celebrated performance units like the twin-turbo V8 N63 and the naturally aspirated N62.
