Hello there, need some inputs. I just got a 2021 XC90 T6 barely 500 miles in it right now. I noticed that whenever it is in dynamic mode and the shifter is on drive and your foot is on the brake/vehicle not moving, the engine sound is louder like a grinding/ heezing sound. But if you let go of the brakes and start moving even without stepping on the gas pedal the sound goes away. It only happen when it’s in dynamic mode.
is that normal or something to do with the supercharger.
Thanks in advance
