Usually it’s more pronounced after a short drive and it happens if I drive or it’s in Park. I can’t notice it in idle, it’s only noticeable when I rev the engine. Its 2018 Kodiaq 2.0 TSI 4x4 engine CZPA. I will upload a short video of the sound as I am reviewing the engine. I tried to diagnose it with ChatGPT and it thinks it’s a resonance from something loose like heat shield. I replaced the serpentine belt and checked all the pulleys and they seem to be fine. I am just can’t figure out where the source of the sound is its very specific. I also excluded the timing chain as the deviation is under 1 degree ( with OBD eleven). I also scanned for codes and there isn’t anything there. A4B4A61C-65FD-4E11-8070-ABEB9F474DA1.mov
