I have a 2011 ML350 Blutec which had the turbo replaced- but 5k miles later and I hear a spinning sound that occurs at peak rpms just before the transmission shifts- it started when I got it back from the dealer but just haven't taken the time to let them fix it. Anyone had similar problems? There are no check lights and it seems to get super heated on short 5 mile trips- I can smell the really hot metal and I hear the metal expanding when I turn the motor off and the cooling fan tries to cool it down as well--
Anyone??
Thanks Ed
