Disadvantages of the Fiat 186A9000 engine
- This is a simple and resourceful diesel engine, and there are no ever-falling intake flaps here;
- Bosch fuel system is reliable, problems appear only at high mileage;
- Most often this is expressed in strong engine vibrations, as one of the nozzles is pouring;
- Also, the engine can often stall due to clogging of the dosing valve on the injection pump;
- The weak points of this unit include the mass air flow sensor, the EGR valve and the booster pump.
