Yet the 318i produces around 156hp, the 320i around 184hp, and the 330i around 258hp. How does the same engine produce three entirely different power figures? The answer matters practically, especially when buying a used BMW engine as a replacement.

The Engine Code Is What Matters, Not the Model Badge BMW has used the same engine across multiple models throughout its history, and this is where the opportunity lies when buying a second-hand BMW engine. The B47 2.0-litre diesel, for example, is found in the F30 3 Series, the F25 X3, the F15 X5 20d, the G30 5 Series, and a number of other platforms. If you are replacing a failed B47 in an F30, you can source a B47 from a written-off X3 or 5 Series and use the same engine, because the engine itself is t...
