Disadvantages of the Fiat 186A9000 engine
There are no ever-falling intake flaps in this straightforward and clever diesel engine;
The Bosch fuel system is dependable; issues only arise at high mileage.
This is typically manifested as intense engine vibrations while one of the nozzles is pouring;
Additionally, a clogged dosing valve on the injection pump can frequently cause the engine to stall;
The booster pump, the EGR valve, and the mass air flow sensor are this unit’s weak points.
