BMW N47 is a four-cylinder common rail diesel engine that has many improvements over its predecessor, the M47.

It features the exact same performance figures on paper as the regular 116d (which utilises the D20 in an 85 kW variant) despite the smaller engine size.

This version featured exceptionally low CO2 emissions of only 109 g/km (6.2 oz/mi) and fuel consumption of 68.9 mpg[clarification needed].

The 150 kW (201 hp) model was used in the Later, the engine received an update which boosted the output to 160 kW (215 hp) and was used on these models: The N47 engine family is prone to excessive timing chain wear and premature failure.

At times the failure has resulted in a dangerous cut out of the engine while the vehicle was being driven - sometimes at relatively high speed.

The return spring on the turbo's wastegate was not originally lubricated or covered, this frequently resulted in early failure causing the waste-gate to remain partially or fully open.

If the vacuum hose supplying the EGR cooler bypass valve gets a hole rubbed in it, or breaks down from old age and oil spray, the EGR cooler won't get bypassed during the engine warmup period.

This causes excessive buildup in the cooler matrix, and when the engine warms up these solid chunks of buildup can detach from the EGR cooler and get sucked into the plastic intake tube, melting holes in the intake tube, causing a massive boost leak and in very rare cases an engine fire.
