Re: Moaning when cold..... 850 1997

My '94 850T has been doing this since new, but only when the temperature is under 40F. The pitch of the sound is RPM specific, most shrill during engine decelaration at about 1600 RPM. A "moan" is a good description for the sound. The noise disappears about 3 to 5 minutes after engine start and stays gone until the next cold start. Had it in several times under warranty for this, but it was always "could not duplicate complaint". The good news is that it isn't any louder after six years.
