    By "noise" do you mean a high-pitched whine, like a police siren--that could be a turbo noise---but it could also be a pulley bearing (for the drive belts) or an alternator bearing.

    No not like a siren, more like buzzing. Hard to describe. Also, there is a noticeable loss of power (takes longer to get up to speed).

    hmmm...I wonder if your boost pressure / intake air temperature sensor, which is mounted on the intake manifold, can make this type of noise?

    Does your vehicle have a boost gauge?

    Is there a way to put the system under pressure to check for leaks in the intercooler/hoses/lines? Would a bad boost pressure/intake sensor show up if I have it scanned for codes?

    I would think that turbo problems would show up in a scan because they would be emissions related. I know for sure there are trouble codes for problems in boost pressure for instance. These are usually in the 230s range.
