Disadvantages of the Mini N18B16C engine

  • First of all, this motor constantly overheats and cylinder head cracks are not uncommon here;
  • A lot of problems are caused by the vagaries of the direct injection system with piezo injectors;
  • Also, the Vanos phase regulators and the Valvetronic system very often fail here;
  • There are many complaints about oil consumption and intake coking on specialized forums;
  • A modest resource in this unit has a timing chain, thermostat and water pump.
