Disadvantages of the Y17DT engine

  • Most of the problems are delivered by the capricious Denso injection pump control unit;
  • Often, it is not the control unit that is to blame for engine malfunctions, but its wiring harness;
  • Valves regularly leak in the pump itself: either injection advance or dosing;
  • Also, oil often enters the cooling system here and there are two reasons for this;
  • Firstly, the heat exchanger is leaking, and secondly, the glasses in which the nozzles are located are leaking.
