The BMW N43 is a naturally aspirated four-cylinder petrol engine which was sold from 2006 to 2013. It replaced both the BMW N46 and BMW N45 engines.[1] However the N43 was not sold in countries with high sulfur fuel,[2] therefore the N45/N46 engines remained in production alongside the N43.

Compared with its N46 predecessor, the N43 features direct injection.[3]

In 2011, as part of BMW's shift to turbocharging, the N43 was replaced by the BMW N13 turbocharged four-cylinder engine. The N43 suffered various problems in service - breakage of the cam chain plastic guides leading to oil starvation as the debris blocked the oil strainer, and problems with the injectors, coil packs and the NOx sensor.
