| If the noise you hear is coming from the turbo area it could be the variable vanes on the '06 turbo. Know if you think it's from the front it is the fan belt. Their is a TSB for this and the dealer will install a "clutched" alternator. Some folks had great results with replacing the belt with a Goodyear Gatorback.
