turbo making loud high pitched sound
I did a search and found that many people say too look at the up pipes, bellows, and v clamps. I dont see any soot on the back wall. It sounds like a screach, only at idle or just off idle. When i give it more throttle it goes away but when i slow down to come to a stop it starts again.
I unplugged the vgt (in park) and the sound goes away. I plug it back in and it starts making the sound again right away.
