Engine Mini W17D14

The company assembled the 1.4-liter Mini One D W17D14 diesel engine from 2003 to 2006 and installed it only on the three-door Hatch in the R50 body in its initial One modification. From 2003 to 2005, a 75-horsepower version was produced, then the engine power was raised to 88 hp. These units are clones of the Toyota 1ND-TV diesel.

Disadvantages of the Mini W17D14 engine

  • The main problems of the engine are associated with fuel-demanding piezo injectors.
  • In second place here is the lubricant consumption due to the occurrence of oil scraper rings.
  • Also, often oil oozes through all the seals due to clogged crankcase ventilation.
  • Periodically there are leaks from the injection pump and failures of the fuel pressure regulator.
  • Still here they often burrow and break off when unscrewing the glow plugs.
