Disadvantages of the VW ASZ engine

  • Saving on lubrication leads to rapid wear of the camshaft and hydraulic lifters;
  • Also, the nests of the unit-injectors are often broken here due to their unsuccessful fastening;
  • The turbine itself is reliable, often only its geometry and the electrovacuum valve stick;
  • If the unit is unstable, check the wiring of the injectors, the EGR valve and the coolant temperature sensor;
  • The weaknesses of the engine include the crankcase ventilation membrane and the ever-leaking tandem pump.
