For Scania 2009,2016 and RJL, there is now only one type of sound and the default SCS sound is replaced by this sound, you don’t have to buy a new engine at a truck service. The green icon again makes the selection of the “with sound for v8” engine easier. For the best sound experience: I recommend using headphones or speakers with a range of 20Hz to 20kHz with a well-matched subwoofer.
