Thanks for the google link, except that is a car rattling when ACCELERATING, as it clearly states in the first sentence. Also that car sound's nothing like the rattle I have.

Mine is rattling when DECELERATING as in when I have my foot off the gas.

However, I'm sure it is the wastegates, I'm pretty used to BMW's shitty products and engineering at this point, and I'm 100% sure they are not going to help in any way. I have no idea why the are a successful company in the US except for people buying them solely for the "look and status".
