VW Jetta / Bora MKIV 1998 Euro,1999.5 US -2005
My Jetta just started doing this... I am not hearing the normal Turbo whistling noise when I give it a lot of gas, however I now hear a squealing noise. Sounds similar to a loose belt kinda whining/squealing ... you hear it just for a moment when you press the gas hard and then it goes away
