Whistle noise

[Josh Machado]

About a month ago I noticed when the needle enters the yellow(2nd) part on the turbo gage, it whistles. Thght maybe this is just normal turbo sound, but again, it only started about 4 wks ago. Its a 2004 9-5T. Is there an exhaust leak? Something else? Im clueless when it comes to turbo's.

Could be exhaust leak, could be air leak into the turbo, could always be the turbo getting ready to call it quits. Get out the inspection mirror, the bright flashlight and give everything around the turbo a good visual examination. Finding this kind of noise is a two man job, finding a cracked pipe or loose hose can be done by one.
