Hello
I have a B6 1.8t with 110k miles. For the past few days I noticed while driving i hear a phantom noise like if i had a supercharger in my car it sounds very weird along with a weird click noise. My turbo feels like it is spooling normally, do I need to clean my PCV system? Or does this has to do with the scary idea of my crankcase going bad? Also when i do hard acceleration the turbo seems fine but I do hear a wee or rinngg while i hard accelerate I do have CXR CAI and FMIC along with a test pipe with no tune and stock tune. Any idea why it sounds like I have a supercharger?
