could be a fuel injector starting to leak. could eventually get stuck open. i'd check it out before it gets stuck open and hyrdrolocks your motor.

Hate to point out the obvious, but take it to the dealer ASAP.

+1 on to-the-dealer. I was going to suggest loose gas cap, which would do exactly what you describe, but you would also have a CEL.

Well, exactly what you described happened to me twice: once in a Z3 and once in a 540i, both times it was the gas cap, both times after someone else filled the tank and both times I got a CEL. With the Z3, it was several days before the CEL came on. Understand you got no light, but betcha it was the gas cap.

was the gas cap not closed properly or was there an issue with it? I am the one who fills gas only and i close it tight every time and double check it

In each case there was no problem with the cap itself, it was just left loose by whoever filled the cars those two times. No way to tell HOW loose it was left initially, but by the time I checked it was clearly loose. On both occasions the gas smell was on initial start up and then tapered off and went away after several miles. On both occasions, those symptoms never returned.
