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.
