C300 sport mode weird sound

Hi everyone I just got my w205 c300 2016 for a month now. I am starting to notice this grinding kind if sound after driving in sport mode for awhile. The sound usually comes out when I accelerate lightly. Especially around 2000 rpm. It sounds like something is grinding but it isnt like a high pitch sound.But when the rpm gets too 3000 its gone. Usually happens after driving on sport or sport +. Bought it back to the dealer and they don't know what the problem. Does anyone have this experience with there new c300?? Thank you

I have exactly the same noise you describe in a brand new C300e, identical story with RPM settings you mention.
Anyone could get information??
