## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED AND THE AIRCRAFT DIVERTED TO MIA DUE TO THE FLIGHT CREW REPORTING THAT APPROXIMATELY AT 10000' AIR BLEED 2 MESSAGE ANNUNCIATION.  FLIGHT CREW RAN ECAM PROCEDURES AND AFTER ENGINE BLEED WAS TURNED OFF PER ECAM ACTIONS WE GOT SPURIOUS MESSAGES FOR ENGINE 2 BLEED LEAK.  THE SPURIOUS MESSAGES WOULD TRIGGER THEN DISAPPEAR BEFORE ANY ACTIONS COULD BE TAKEN.  THIS OCCURRED APPROXIMATELY 6 TIMES. THE AIRCRAFT LANDED SAFELY AT MIA WITHOUT FURTHER INCIDENT. MAINTENANCE REPLACED THE #2 ENGINE THERMOSTAT - FAN AIR VALVE CONTROL AND ACCOMPLISHED A SATISFACTORY OPERATIONAL CHECK WITH NO FAULTS NOTED.
