I noticed when you start the car up the turbo (i'm guessing) kicks in after a few seconds and creates a semi-loud noise. And when turning my car off, you can hear the "turbo noise" shutdown slowly. I understand all that. But recently, it has stopped doing it. It still rides fine, but I'm curious as to why it doesn't have that noise.


It's an '01 2.7T by the way........



Thanks in advance.
