Idle sound for VanHool Doppelgelenk Add-On 1.0.0

Modifies the sound of the idle of the VanHool NewA330, NewAG300 by Agora Citelis and NewAGG300

This is a mod that some people asked me to do because they wanted a more realistic idle sound for the NewAxx, so there we go, to dowload it you have to follow this path: OMSI2 -> Vehicles -> HH_Doppelgelenkbus -> Sound, and you have to put both 87_eng_int_idle and eng_int_idle inside the sound file by opening the .rar file.

Thank you, and I might modify more sounds of other busses and do repaints since this is my first mod
