I've noticed it seems to happen right after driving if I've been aggressive with running through the gears. Not launch control, but let's say you floor it from a stoplight in Sport + and pull up in the garage at home shortly after - several strong drops of rear-diff fluids show up.

I've been keeping a piece of cardboard under the parking spot so I can monitor. I can go days of 'normal' driving with nothing showing up under the car, but again - one stoplight's worth of having 'gotten on it' and yeah - there are those damn black drops.

Being replaced under warranty this Thursday by the Dealer - Replacement diff was air-freighted from Germany.
