Does anyone have any input on if I can confirm it’s wastegate rattle?

So long story short i got off the freeway on my way to the gym. Then at a stoplight I hear a rattle type noise when accelerating, the next day this was the noise it was making. Just want to be sure to classify it as wastegate rattle before changing the turbos. Thanks for any help!!!

That sounds like a bad belt tensioner or loud valve ticking.
It doesn’t sound like wastegate rattle.
If it is wastage rattle, it should be silent when revving the engine and begin rattling when the RPMs start dropping.

Sounds a bit like mine when its cold, does it go away when the engine is heated up?
