Disadvantages of the ENS engine
The regulator valve of the high pressure fuel pump in this diesel engine’s fuel system is typically the source of concern;
Additionally, piezo injectors require more fuel and have fewer resources;
It is not very dependable, and the turbine frequently needs to be repaired after 100,000 kilometers;
Only the rocker breaks when the timing belt, which is intended to last 150,000 kilometers, breaks;
The fuel filter heater connector is frequently the location of air leaks.
