Wastegate Rattle??

Hey guys i was wondering if you guys think i have waste gate rattle my car is an 08 e92 just hit 60k last week. Ive been suspicious of my waste gates cause i sometimes hear ticking near the waste gate area on cold starts but it usually goes away after awhile. Heres a sound clip on youtube

don't hear any wastegate rattle, the n54 makes lots of different ticking noises, valve lifter tick, very loud injectors, evap tick, You say the noise goes away once the vehicle is warm which means its probably the hydraulic lifters (normal). also Wastegate rattle is heard on deceleration, usually as the revs fall through 3,000 rpm sounds almost like leaves crunching.
