Just as the title says, it's very much audible while the car is stationary, occasionally while driving. It's pretty loud and I have no clue what it is, my family member drove it to a local shop as I was away and they told me it was "nothing to worry about" but I kind of don't buy it. It's a 2014 S60 T5 5 cyl.
