so i finally passed 1k mile and am pushing the car harder now. I noticed from a stop or slow roll under hard acceleration, other than the nice exhaust burp sound, i also hear a faint whining noise around 4k-6k rpm. The noise also gets louder as the rpm gets higher. this doesn't happen under higher speed down shift so it's usually only at 1st and 2nd gear. i watched a lot of youtube videos and can kind of hear the same sound. any of you hear this on your gla45 too? thanks guys.

i'm not sure that's why i'm wondering if anyone else hears this too... thanks.

yeah i get it on mine when i get on it in 1st-2nd. sounds like a real real weak whine like a supercharger makes.
