Brava 2001. That helps, but I'm not familiar with the Brava Units.
Hopefully somebody will come to your rescue.
If you have a working relationship with your Fiat dealer (e.g. they service your car or you bought it from them etc. then they should get your code free of charge.
If they won't then I would approach Fiat customer relations (they have a free 0800 number) and ask them to get it for you. If they give you a hard time then given them a hard time back, Its Your car, Your code(s) that Fiat chose to squirrel away with NVRS (National Vehicle Security Register) and keep back from the customer.
I've had a long run-in with Fiat in the past over NVSR procedures and they are perfectly aware of the holes/stupidity of some (not all) parts of the system/agreement they have with the NVSR.
Sorry I can't be of more help.
