Losing some coolant

Cranked up the car today ('06 330Cic) and the coolant light came on. Expansion tank was empty. Topped it off with a 50/50 mix of BMW coolant, a total of 28 oz. No light when I put it in the garage the night before, and no leakage on the floor. I assume it finally just got down to the point where it triggered the light.

Any suggestions? It's not the transmission thermostat O-ring; I replaced that about 8 months ago and no signs of leakage there.

I'm off to the dealer later this week for the last visit prior to the CPO warranty running out. What should I tell them to look for? Car has just under 70K on the clock. I assume if it was the expansion tank it would be a catastrophic leak... Any suggestions/assistance are appreciated.
