I have 2010 volvo s80 t6. About week or so ago, it started making a metallic grinding sound when I press the gas pedal. It mostly does it when the car is cold but will still make the sound when warm, but not as loud. And the sound is most noticable at slower speeds (20-40mph), it does not make the noise when in park or neutral though.. only in gear. Any idea what it may be?

 

Hey man, I’m having the same problem. I know this is old but did you ever figure out what it was. Thanks
