## Discrepancy

DIVERTED DUE TO APU OIL SERVICE INDICATION AND INOPERATIVE LEFT ENGINE GENERATOR.    R GEN DF'D INOP AND APU OIL WAS SERVICED PRIOR TO DISPATCH.  APU STARTED TO HAVE HIGH OIL CONSUMPTION LATER IN FLIGHT DUE TO LEAKS. NO EXTERNAL LEAKS OR REPORTS OF OIL FROM SEAL DRAINS, LOSS IS THRU TAILPIPE - LIKELY SCAVENGER PUMP FAILURE.  REPLACED APU.
