Disadvantages of the B5254T4 engine

  • The main complaints of the owners here are related to failures in the phase control system;
  • Often there is a decent consumption of lubricant due to clogged crankcase ventilation;
  • After 150,000 km, the main culprit of the oil burner is the wear of the turbine shaft;
  • The timing belt may not pass the prescribed 120,000 km, and when it breaks, the valves bend;
  • The weak points of the motor also include a pump, a thermostat, a gasoline pump and its supports.
