Hi folks. I am having some issues but I don't know why. I have noticed couple of months ago when full load there was some squeak noise coming from turbo (I think) or something like air leak. Today I have noticed that a strange sound while throttling, the sound is noticeable in idle also and when you press the gas pedal. If you press the gas pedal there is a loud "whooooo". I have uploaded a video too so you can hear the sound. I tested using VCDS with no errors and the turbo seems making pressure in the range of the specification values. Is it the turbo or n75 valve? The uploaded video sound is 2000+ rpm. The car is Golf 5 1.9 TDI 2005.
