2016 Audi S4 Weird Loud Engine or Supercharger Noise with RPM/Revs

[sergcool]

Hello everyone.

A couple of days ago my engine started making weird noise which gets louder and quieter with RPM/Revs.
I also noticed from the location of the supercharger, it started being way louder almost knocking/tapping.

I think I remember having before, similar tapping noise when I just start the car, but then it would go a way once the car warms up. I might be mistaken though.

What might this possibly be?

Update: Scanned for codes and I got P052E00, PCV issue? Researched a bit online and people say that Audi Crankcase Breather Hose - VNE 06E103207AP might be bad.
Could this be the cause of the noise which happens with the revs? This is my daily driver and I want to make sure with my constant driving, I don't make things worse.

Yea you need to replace the PCV hose running to the PCV/intake hose. I’d check first make sure the hose didn’t get knocked off or something, it sits on the intake hose right before the throttle. Most likely gonna have to replace the hose and PCV breather, parts are a couple hundred and requires taking the supercharger off. Plenty of info on Audizine about PCV replacement.
