Check the oil level just to be sure it is not overfilled. If a dry sump excess can dump into the air intake.

Oil smoke is blue, coolant makes white smoke. What were you doing with the throttle when you saw the white smoke.

... or it could be just steam if it’s cold. I’d still get it checked out by the dealership to be safe. As mentioned, burning oil is blue, and coolant is white. The exhaust smells different too.

Some suggestions:
Unburnt fuel – do you smell fuel? – have fuel system checked out.
Coolant leak into engine – check coolant level and pressure test and check for leaky head gasket.
External coolant leak – check coolant level, visually inspect cooling system and pressure test.
Water vapor – water accumulating under car and spilling onto hot exhaust or water splashed up onto hot exhaust and evaporating.

White is coolant IF there is a coolant leak getting into the engine. Is your coolant level ok?

My '16 did that once last year. It hasn't done it again, so I'm not to worried. I have no idea why it happened, or if it will happen again. It looked just like steam when a car is first cranked in the cold, and dissipated as quickly.
Please keep us updated as one never knows when they may need the info. Good luck, I hope it's nothing serious on yours.

Funny, I am also an A8 Arctic White in NW Washington!
The reason i asked is that my car was belching a bit also and it seemed related to the AFM.
Since I put the Range device on, no “smokie tail”.
