Hi,
The flashing gas light is indicating that fuel is somehow escaping out from around the cap. I had the same issue with my E430. Turned out the cap wasnt secured properly. Once it was, the light went away.

Yes. If the ECU detects gas vapors escaping, it will trigger the check engine light. In my case, the light went away by itself after 2 days.
