Disadvantages of the D16AA engine

  • A known but rare problem with these engines is airing the oil pump.
  • The reason for this is the drying of the sealing ring between the oil intake and the pump.
  • Also here there is fuel getting into the lubricant when burning the particulate filter.
  • After 100 thousand km, the EGR cooler often leaks, and sometimes its casing simply bursts.
  • At high mileage, the EGR valve often becomes completely clogged and jammed.
