Hello everyone, thanks for your feedback.
The blinker sound is disabled, but can be enabled with the following setvar: vis_blinker_sound
The add-on got a new update with modified sounds, and lowered engine sounds with better transitions. The next update will fix the S416nf, and the model errors (doors and assignations, for example).
If you have anything else, or something about the new sounds update, I'm waiting for your wishes
Thanks!
