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.
