The 1.6-liter Mini Cooper N12B16A engine was assembled at a factory in England from 2006 to 2010 and installed on the mass versions of the Mini in the back of the R56, as well as the Clubman station wagon in the back of the R55. A similar power unit was installed on Peugeot-Citroen cars under its EP6 index.

Disadvantages of the Mini N12B16A engine
- The main problem of these power units is oil burn and intake coking.
- A rather modest resource here is the timing chain and especially its tensioner.
- Also, the Valvetronic system and Vanos-type phase regulators serve relatively little.
- All engines of this family are famous for regular oil and antifreeze leaks.
- The weak points of such motors include a thermostat, a water pump and lambda probes.
