Sounds like it's coming from a belt/ pulley. You could try spraying some wd40 on the belts as the engine is running one belt at a time to see if the sound stops..wd40 actually makes rubber more grippy believe it or not.

Ok but when I open the boot for engine, the sound isNOT somewhere from the belt, the sound is intensive from the space of the front wheels,
I was also thinking about the belt,... but is it normal for a new car, that has not 30000kms?

I just drove again around 60kms but now the sound is gone
It probably happens on cold starts

jcdub: do you have experiences spraying on belts of the engine?
thanks
