So, I've got the addon vehtypes file. The sirens of the Ford Mustang Cruiser works, but the siren of the American LaFrance Eagle and other siren vehicles do not work. Reverse beep sound works.

What you describe is really weird. But, have you downloaded this file?
If by "not working" you mean that the flashing lights work but you don't hear any siren sound, that's another random weird problem of the game that doesn't depend by that file.

I don't mean that, I've downloaded the file from MM2x. And when I start siren the game crashes. Also with the default fire truck but not with the Ford Mustang Cruiser.

The situation you describe sounds the one of a files conflict, especially because I suppose you say that it happens also with other add-on cars with sirens. Make sure you haven't another vehtypes.csv file present in one of the .ar files placed above the !!!!!addon_vehtypes.ar file in file name sorting. To quickly fix that, rename it adding some space between each "!" symbol.
The addon_vehtypes.ar file available at MM2X has all the three default cop cars type basenames (Ford Mustang Cruiser, American LaFrance Fire Truck and Silver Eagle Fire Truck), besides the many others about add-on cars with sirens.

Addon Vehtypes is on the top of all addon cars and has all the names of siren vehicles in it but the game still crashes when the siren button is pressed.
