## Discrepancy

WITH THE NR 2 IDG ON MEL REQUIRING OPERATION OF THE APU DURING FLIGHT, THE CREW RECEIVED AN APU OIL TEMP MESSAGE ON EICAS.  THE AIRCRAFT DIVERTED TO LIT AND LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE APU OIL OVER SERVICED AND REMOVED EXCESS OIL TO THE CORRECT LEVEL.  THE APU HIGH OIL TEMP SWITCH WAS CLEANED AS WELL.  THE APU THEN OPS CHECKED SATISFACTORILY.
