Disadvantages of the ENR engine

  • The weak point of the fuel system of this diesel engine is the high pressure fuel pump regulator valve;
  • Piezo injectors also have a low resource, and besides, they are very difficult to remove;
  • The turbine here is not very reliable and may require repair even up to 100 thousand km;
  • The timing belt runs about 150,000 km, and with its breakage it usually only breaks the rocker;
  • Often there is air leakage through the fuel filter heater connector.
