If the wastegates arent holding boost - or holding boost irregularly youll notice lag and stuttering.
The rattle is very hard to pick up. The only surefire way to hear it is drive down a street lined by parked cars, downshift and let the car slow down on engine vacuum.
When you do that youll be able to pick up on a ratcheting noise coming from under the car.
Also just take it to the dealer. Say the car is having acceleration issues can you check the turbos. Theres a warranty extension/possible recall out on the turbo wastegates and theyll do the functional testing on the parts for free. Nothing to lose.
