Mine is just the opposite-happens when it is fully warm. Have 9700 miles on the clock. Seems early in the game for a wastegate rattle. Where would the rattle noise come from?
Would it sound like it's coming through the dash?
I posted a thread in the N55 section about rattle from the engine bay with video. A trained ear can hear the RPMS peaking and making a buzzing rattle sound.
