Door script sound

Hi all.

I have a question aout the doors.
Can the script be modified to delay the backdoor closing after 2 seconds of the sound begins?
I have tested the sound, but i can only overlay the closing warning, if i extend the sound file, it will desincronyze the closing movement and sound.

And another question.
About the stop signal, whan the light on the dashboard lights on, can we add the warning sound?
Like in the Lion's city and Citaro, and so ever.

I will try to mod this, but i need some help and advices.

Thanks in advance.

if you like, I can send you a recording of an O305 Warning buzzer that I made. which you can try to script in.
