Changelog 3.0:
Last week, I recorded a NG Scania engine sound in real-life and used the recordings for this sound mod. The whole motor sound is made from the sound files I've recorded myself and I think it sounds pretty good.
I've also added a working fan sound that is randomly on and off. This makes the mod a lot more realistic.
My new interior sounds, which have already been added to my V8 sound, are now also included.
