Faint metal squeal sound audible at low speeds while off accelerator

[SlippyFist]

So.. i may be retarded, because i can't tell if i'm hearing a turbo sound or if i'm hearing some other mechanical sound. basically i recently noticed a very faint squealing sound while the car is moving forward at low speeds- it's VERY LOW, only noticeable while driving ~20 mph in first/second gear with music all the way down. The weird part is that i only hear it when i let off the accelerator and it stops when i press it again. that's why i said i wasn't sure if this was some vacuum noise or something related to the turbo; i admit this is the first car with a turbo that i've ever driven so i'm still not fully familiar with it.

it doesn't sound like it though, like it sounds like a "bad" sound- like a bearing is rusty/squeaky or something. actually it reminds me of the sound your wheel makes when a rock gets stuck between the rotor and that shield behind it, except when that happens it's very very loud and scary and isn't dependent on whether the accelerator is pressed or not. again this is a very quiet sound, it's hard to hear over just the normal driving sounds, and it gets drowned out as you pick up speed and continue driving.

i can try to record a video of it tomorrow while i'm driving around my neighborhood but i'm hoping you all just tell me i'm retarded because it's some other normal sound.

I have the same sound. I’ve been told it’s normal.

Electronic wastegate. Disturbing but normal.

I hear something similar, but to me it sounds like when brake pads are running low.

I joined this forum for this specific noise mine is annoying.....and sounds like a break wear indicator making contact with the rotor....smh

But in this forum we have so much more to offer! LOL.

Well I'm now in the wastegate noise club. My factory unit wasn't very noticeable but my MHI stage 2 is annoying. I might try some high temp lubricant to help fill in the voids some.

Hahaha trueee

Does anyone have a small clank when letting off the gas between 3-4000rpm or is that the exhaust ?

Mine makes the same noise. It's very faint on decel. I thought it was a loose bolt on a heatshield. So the general consensus is its the wastegate?

appears so. it's one of the worst things about this car honestly lol it's such a terrible sounding noise, i literally can't believe it passed honda's QA lol. in fact the other day i finally got a rock stuck in my rotor shield for the first time- and i didn't notice it at first because i thought it was the stupid wastegate noise!

Lmao!!! Well nothing a little radio music can't drown out

I wonder if the wastegate sound is different on different cars. It's not something I ever even noticed.
Maybe I'm just always on throttle, LOL.
