Be careful with any clank noise at acceleration, it's rather general and may indicate other problems.
For the known wastegate rattle issue, rev the engine to 3-4k RPM then on engine deceleration you'll hear the rock-in-tin-can rattle sound with hood open and windows down.

You may have problem with exhaust butterfly which is more normal, but so is control arm bushing, trans or diff so get the dealer check it while it's still under waranty.
