Disadvantages of the Fiat 939A3000 engine
- The main problem of the engine is falling off the intake swirl flaps;
- In second place is the not very durable oil pump and balancer drive chain;
- The turbocharger is reliable and often only the geometry change system fails;
- Due to a clogged particulate filter, an expensive block head often leads here;
- The weak points of the motor include the mass air flow sensor, the EGR valve and the crankshaft damper pulley.
