Disadvantages of the EXF engine
- Most diesel problems are related to malfunctions in its fuel system;
- Even before 100,000 km, the high pressure fuel pump may fail or the injectors may start to pour;
- Often there is oil starvation due to the sinking of the heat exchanger valve;
- The turbocharger here is quite reliable, but its nozzles burst regularly;
- Often the thermostat and the damper actuator for changing the geometry of the intake fail.
