Disadvantages of the Fiat 939A3000 engine
The engine’s primary issue is the intake swirl flaps falling off; the weak oil pump and balancer drive chain come in second;
The geometry change system frequently fails, but the turbocharger is dependable;
An expensive block head frequently results from a clogged particulate filter;
The mass air flow sensor, the EGR valve, and the crankshaft damper pulley are the motor’s weak points.
