Disadvantages of the ENR engine
The high pressure fuel pump regulator valve is the diesel engine’s fuel system weak point; piezo injectors are scarce and challenging to remove; the turbine is unreliable and may need to be repaired up to 100,000 kilometers;
The timing belt typically only breaks the rocker when it breaks after 150,000 kilometers. Frequently, air leaks through the fuel filter heater connector.
