My turbo started making a high pitch "whistle" or whining noise a few weeks ago, especially when accelerating in 1st, 2nd and 3rd.
At first, I could still hear the turbo boosting and it seemed to be driving okay. However today, there is a whining noise that has suddenly become MUCH louder and happens consistently even when touching the accelerator lightly. When revving in neutral, I can also hear the whine. It's an "air-y" sort of noise. I can't really hear obvious scraping coming from the turbo but it's really hard to tell.

Is my turbo stuffed? Thanks.
