They also have some guidelines on what is "normal" rattle. This is a mechanical device it does make some noise.
Only reason I got both turbos is because my car ended up with a new model turbo and an old model turbo installed at the factory. When the tech tried to work on them they were different and BMWNA told him to replace both.
ah, i'll try to make sure the issue i'm having is replicable and then bring it in to see what they can do. thanks
