I'm no expert but would think it is the relay. Should be an easy enough fix: Take off the fuse panel (in front of the passenger) and replace the broken part. One place to get the part from is: http://www.italiancarparts.com/parts/308.html Turn Signal / Flasher Relay (RP), all 308 models: #fr60254208R $27.95 But first I'd check the fuse.
Most people look for the more difficult solution first when it comes to an 'exotic', rather than the easiest! A Ferrari is a car, they all work basically the same.
