2024 x7 Check engine light

Hi All:

First post on Bimmerpost.

Bought a used 2024. Been running it for a few months. Awesome vehicle.

Recently (for the first time) - filled Octane 93 at Costco. I drive for 2 mts - CEL comes on.

Code is P04FC. Something to do with Gas Tank Cap. I tried to clear codes but did not help.

I will take to dealer but just wanted to hear any thoughts.

The code is related to the crankcase vent system, but check the oil cap first.
