    Does this sound like a boost or exhaust leak? Heard this for the first time when I pulled I to a parking garage.

    Sound starts as I give it gas and then fades away a couple of seconds after I let off.

    Check your air box lid and intake piping. All pressurized air is metered through your MAF sensor. The ecu usually picks up on a leak and you should be able to review your fuel trims and compare them to other cars to see if they are off. I would think that a code would be thrown if you had a boost leak but maybe others on here can speak from experience.

    Looks like it makes two of us. The only difference is that the sound is pronounced over 2k and with the car driven in 95-100 deg heat for half and hour or so (really hot engine). Also, i’ve been driving like that for over 2k now. Same mpg, same car performance (so it seems). 40K on clock, no tune. What’s your mileage?

    I have a similar noise when accelerating. I'm at 20k miles with a tune. I noticed the sound become more pronounced after I changed my air filter but as far as I can tell no leaks in my piping. What filters are you two using?

    Turn car off, Open your hood, pull the tabs back on the air filter cover, lift the cover up and check the filter to make sure that its even there and that it is clean. I promise it’s not scary.

    It’s 4 screws for the 1.5T, but the 2.0 it’s 2 metal spring clips. No tools required

    My other suggestion would be to just look around the engine and make sure all hose connections are good. If so then I’d take it to the dealer to find out what it is.

    All hoses are tight and no loose connections. True, dealer would be the way to go although i’ve been this route before, until it shits the bed they will act like there’s nothing wrong. Have 0 desire waisting time dealing with those crooks. Will drive till it breaks and then address, plenty of warranty still left

    no, nothing at all. feels the same. obviously, the car is a bit sluggish as it always is during the summer heat. still delvers 37mpg with mixed driving.

    You have the same sound!? Nobody was responding so I thought I was alone.

    I've noticed that mine more noticeably happens when it's hot out. What if something expands when it's hot, making the sound?

    Same here. No sounds with ambient temps below 90. Once above and some highway driving, it comes back. No clue what it is and won’t make a move till something breaks
