im hoping someone with a 2016-18 wrx can help answer this question of mine, but im open to any opinion really. So i have a stock 2017 wrx (automatic) that has been making a sound i am unfamiliar with.
when i am slowing down and passing 35-30km/hour, my car makes a quick whistle/chirp it might happen after my car has been in boost and i am trying to figure out why its happening. also sometimes when i am accelerating over 30-35km it will make that whistle/chirp sound again. now, this isnt a regular turbo sound im used to when it hits its peak and makes the "woosh" sound, or flutter type of sounds as my car is all stock.
a theory my friend had is the turbo is letting off a bit of pressure and thats the sound im getting, but it almost sounds like an older cars belt squeeking (mind you it only happens at that one speed and one very quick sound). does the stock wrx make any sounds like this normally? the tech at the dealership was saying it might be because of the wastegate, but he never did get to hear the sound as i couldnt Recreate it for him (figures).
now, if it is a normal sound, great. but i am trying to understand why it is happening. i feel like if i were to try and sell it that it would screw me over also. does anyone have the same vehicle that might be doing this? or have knowledge as to why its happening? im going to attach an audio clip, its myself making the sound, but its exactly what i hear...
