Disadvantages of the X20DTL engine

  • Most powertrain problems are related to the Bosch VP44 fuel pump;
  • The weak point of this injection pump is the fuel valve control transistor;
  • If the fuel filter is incorrectly replaced, you can simply air the system;
  • Due to the drying of the rubber gaskets under the nozzles, the oil enters the diesel fuel;
  • Also here, the EGR valve is often overgrown with soot and the EGR valve is clogged and the particulate filter is clogged.
