N55 wastegate rattle?

N55 wastegate rattle?

---

So on a cold start if i try to get onto any kind of boost, it will rattle (just like any normal wastegate while it is settling)... Now when the car is warmed up and i get on it a little bit and let off, i hear the tiniest slightest turbo rattle (i have to really try to listen for it). The car holds boost great. I heard a tiny tiny amount is normal. The car is a 2013 335i e92 6MT with 24k miles on it. I do have just jb4 g5 ISO on the car with chargepipe with proper settings. Should i be worried and take it to my SA? The car is under warranty until July 2017.
