No. Wastegate rattle does not throw a code. I would open a case on this one, something isn't right. Sounds like you have a BMW NA rep that has no idea what's going on... There's a service bulletin out there which accompanies they extended turbo warranty (82k miles) that I think references rattle, but no faults. You might want to present that doc to the rep to see if it helps. You also may want to try to (politely) speak with their supervisor on the subject.

Just my $.02

I had my turbos replaced at 44k. No fault codes, no hastle.
