From my understanding looking into it, it does seem that way. Just really frustrated with this noise, it just sounds like a bird or cricket in the engine or something.
Inde shop said same thing one of the mechanics had a 2021 and no noise. They said the noise seems to be coming from high pressure fuel pump/turbocharger area. Allthough to me, it doesn't seem like any of those things going by the noise. It sounds almost like a diff noise so more likely to be pulley, belt, tensionor, bearing, something of that sort because it gets more rapid is you accelerate and a little louder.
I will keep pursuing it because it drives me absolutely nuts as the car is perfect otherwise.
There are a few high quality youtube videos of the 2020 POV drives where you can hear it on light and steady acceleration. That's why I think this is a 2020 model problem
