BMW B47 Engine Guide

Engine: B47

Bulletin text

The B47 is BMW's 2.0 liter four-cylinder common-rail turbo diesel and the engine that followed the N47. BMW's workshop data lists it at 1,995 cc with an 84 mm bore, a 90 mm stroke and 16.5:1 compression. BMW's parts catalog lists the B47 only on vehicle types for other markets and has no US-market vehicle type with a B47 engine code. The B47 was not sold in US-market BMWs, per BMW's own vehicle lists (data to December 2019), so this is a short guide.
