Do you have any mods to your exhaust? I started noticing the noise when I went to the AE exhaust. It started out as you said noticeable with the a/c but then now it's at a point where it's loud as eff all the time. I feel like it has something to do with the back pressure & how my worn out ass Wastegate actuator slop reacts to the OTS Cobb tune.

FWIW- On that note I went ahead and uninstalled/unmarried the Cobb for a couple of days and the noise went away
I have the golf tee mod but thats it. I also just realized that this is the n54 subsection and I have an n55, I just came across this while I was searching but I have the same problem :/. I'm planning to buy an exhaust and install them at the same time. It started out being the full time I was stopped but now it goes away after a couple seconds... I'm going to take my mods off and see what the dealership says.
