Rattle on deceleration, Wastegate?
I have a rattle from the front of the car on deceleration. I read that someone had a rattle like this because his wastegate had gone bad. does this sound like it could be my problem?

He is what my brother and I did...
With the hood open, turn the throttle plate by hand. Take a metal rod about 1/4 inches in diameter and touch it against the turbo. If the turbo is making the sound, you will clearly hear the sound coming up through the rod. You will need to put your ear up against the rod to hear the sound.
Another method is to use some hose as a makeshift stethoscope. We tried this first, but the hose was made of silicone and it melted.
I referr to the sound as "the rattlesnake." It sounds like some marbles being rattled in a coffee can.
