Default Hissing Throttle

I have a 2015 Turbo S. 200 miles on it. As I drive it I hear what can only be described as an annoying "hiss" for 2-3 seconds when I let up on the throttle.

Even at low speeds, (or from a stop, for that matter), I step on the throttle, speed up to 20-40 MPH, and when I let off on the gas I can hear "hisssssss." It sounds like a vacuum sound, perhaps. I can do it every time.

Anyone have an idea what this may be? I will take it into the dealer in the near future, but it annoys the heck out of me for now.

Could be a boost or vacuum leak. Not large enough to set a CEL.
Best to take it in.

This is why the TTS comes standard with the Burmeister.

Turn the volume up just a bit.

Problem. Solved.

Burmeister is an option on the TTS....$3500. Should be standard.

The 991 Turbos are very complicated machines.Get use to the noises and enjoy them ,that is what I did.If you do not have a CE Light and the cars runs good don,t worry about it....

They are also very smart,it their is a issue,it will tell you...
