I too have an issue with an odd squeal noise. Just started a couple weeks ago after a heavy cold snap. Comes on around 3k rpm while accelerating under load, no matter the temp. Cant verify that a specific turbo boost is causing it, or that its the turbo at all, only that its around 3k rpm and mid to upper boost levels. Sounds like its right in front of my steering wheel or radio.
Upon some research, i think it might be my fuel cooler/turbo actuator........low on coolant? I did recently have the coolant flushed.
