Is you car still under the manufacturer's warrenty? It seems like a good idea to take it to the dealer to get it checked out.
Unfortunately I do not have any warrenty Anymore.

Sounds like a possible injector replacement, had the same issue on my old 2010 a couple of times! Same sounds, does it reset when you turn it off then return intermittently?
I have checked what you said. But the sound remains when I return it on intermittently.

Can It be because of the wrong engine oil or the gasoline quality?

I checked the last oil service and they put in 5w30 CASTROL which is approved by BMW.

And as last. could this sound not be normal because when I close the hood. I cannot hear the sound.
