Rattling sound when letting off gas: Wastegate problem?

My car is making a rattling snare sound when i let off the gas when either in manual mode (drive) or parking and revving the engine. The sound gets less aggressive as the rpms drop down, and it goes away somewhere between 1200-1700 rpms. There is no rattling at idle.


Any ideas to what it is and do you think it is serious enough to get it checked out under CPO before it develops into a more serious problem?
Thanks!
