I have had an 05 tC since July. For the past 6-7 months I have had a periodic whistle coming from an air leak somewhere in the front of my car. It occurs at speeds above 65mph but only about half the time I am at those speeds. A whistle is surprisingly hard to locate. I think it sounds like it is coming from the front driver side corner of where the dash meets the windshield. Ive had passengers that think it is coming from the front of the sunroof, but when the sunroof or windows are open you can still hear it. I know I can take it into the dealer, but I'd like to have a clue before I take it in. Usually if the dealer has an idea to focus on they are much more efficient. And they may not be able to recreate the sound.

Does anyone have any ideas or a similar problem?
thanks!

 

hmm... Not a whistle, but the car is pretty loud and when just sitting at a stop light I can heard a deep deep humming sound. Not sure if anyone else experiences this?

 

does it make the sound when you step on the gas?

 

yeah, perhaps it's just your intake: http://home.cfl.rr.com/icdedppl/faq.html#f1

 

Mine makes a whistling noise when accelerating...I was wondering what that was too?!?! Sounds as if it is coming from the front passenger side...

 

jesus people, the intake is on the front drivers side, I think if you post a my airbox whistles/I got an air leak thread you should get banned. SEARCH BUTTON.

 

yesa i aslo hear a whistling noise, it always happens right when i shift. it kind of sounds like a turbo spooling lol other than that the ar rides fine

 

This is not an intake problem. It is way to loud, the loudness changes, it is not related to acceleration, and it does not happen every time. It is definitely not a design. It is a problem. If anybody else has a mystery whistle please let me know if you have found it. Thanks!

 

havin' a bad day are ya?

 

must be a newbie because it was one of my first posts on this site. its fine its an a perk to me

 

yup. it's the intake sucking it all in.

 

lol... yea or like my tranny is so loud makes a whinning noise

 

Yea its ur stock airbox or intake. It sounds louder when there you are in between buildings/trees/cars and quieter around open areas because of the way the noise bounces off objects. One day i decided to let a friend hold the top part of the airbox while i revved and it was the same noise i heard, just alot louder. Anyways, the airbox is located on the drivers side, almost on top of the wheel.

 

the tranny does whine I will admit that

 

the sound is coming from your throttle body.

all TC's have this sound and this topic has been covered nearly a 100 times. please do a search before hand. :D
