Disadvantages of the ENJ engine
- The diesel engine is equipped with a reliable Bosch injection pump, but the control valve often fails;
- Also, nozzles are not the highest resource, sprayers fly into them;
- The timing belt runs about 150,000 km, and when it breaks, it usually only breaks the rocker;
- Due to the destruction of the membrane in the crankcase ventilation valve, the flow meter often becomes dirty and fails;
- Other weak points include a thermostat, a booster pump and a crankshaft sensor.
