14 STi

Default Strange noise at speed

Hi all,

I currently have a '14 STi hatch (with COBB AP stage1) and finished a long trip over the weekend. I'm trying to figure out if anyone else has this issue and an idea of what might be causing it.

At approximately 80mph (in 6th gear) when I press the accelerator (around 5-10%) a strange humming noise appears to be coming from the driver side. If I push the accelerator beyond 10-20% it goes away immediately. I played with this quite a while trying to accelerate and what not but holding steady speed with minimal throttle kept the noise going consistently.

The noise also kinda comes up here and there when decelerating through 85mph to 80mph or so around where I would be pressing the gas just a little.

Just to note, the sound immediately disappears with extra acceleration and going faster than right at 80mph doesn't make the noise.

I've tried searching and didn't really find much so any help is appreciated!

make sure you clean you car of everything before you hunt for strange noises

The noise only occurs in 6th gear? How about 80 mph in 5th gear?

On certain grooved highways I hear some tire thrum but the noise is not speed dependent like yours appears to be.

Any chance you can create a video of the sound?
