Disadvantages of the VW NZ engine
This engine is dependable and structurally straightforward, and the majority of its malfunctions are caused by aging.
Repairing the Digijet control unit is the most challenging aspect of this situation.
Low resource is another characteristic that sets apart the coolant temperature sensor and ignition system components.
Periodically, the throttle assembly and fuel pressure regulator need to be serviced.
Oil may be forced through the dipstick by the freezing crankcase ventilation system during the winter.
