The initial fume event (at the gate) was determined to be the result of an over serviced APU. The aircraft had just come out of a weekly inspection earlier the same day. I suggest mandating a new procedure to insure that APU's aren't over serviced.
A321 First Officer reported fumes during preflight suggesting the APU was likely over serviced.
