Disadvantages of the ENS engine
- In the fuel system of this diesel engine, the regulator valve of the high pressure fuel pump is most often worried;
- Piezo injectors are also more demanding on fuel and have a low resource;
- It cannot be called very reliable and the turbine often requires repair up to 100,000 km;
- The timing belt is designed for 150,000 km, but when it breaks, only the rocker breaks;
- The place of air leakage is often the connector of the fuel filter heater.
