Disadvantages of the Alfa Romeo 839A6000 engine
- This is a simple and reliable motor, and many of its problems are caused by poor wiring.
- Also, a lot of trouble here delivers a booster pump, a mass air flow sensor and an EGR valve.
- Strong engine vibrations usually indicate that one of the injectors has begun to pour.
- The turbine runs well, often only the system for changing its geometry fails.
- Another weak point of the diesel engine is the not very durable oil pump chain.
