Disadvantages of the Mini B48A20A engine

  • In engines until 2017, timing chains quickly stretched, but then the design changed;
  • Quite often, idle speed floats due to a failure of the tank ventilation valve;
  • After 100,000 km, valve stem seals usually tan and oil consumption appears;
  • At high mileage, failures of the Valvetronic system and Vanos phase regulators occur.
