2011 C300 Engine Whine

Does anyone know if there is a fix for the irritating whine from the 2011 C300 engines? Two different dealer techs have told me the whine is totally normal which I find hard to believe. It seems to be most audible around 1500-1800 rpms. Any advice would be appreciated. Thanks.JJ

Sorry I can't help you except to say that doesn't sound normal to me either.
