i have a 318 uk bmw, it's 1992 year. the problem is when i set the alarm if i open the doors the alarm will trigger the lights will flash but no sound comes out. some said that the alarm siren might be turned of but i can not find one on it. Can Someone help or tell me where it is

try looking for the alarm siren wire under your hood. if it's cut or disconnected then that's the cause why it has no sound.

It's usually in one of two places: directly behind the passenger side headlights, or next to the 12v post.

Thank I've looked about it not there, i think someone has taken it out.
Thanks for your Help

If someone has previously removed it... well my best option would be to go to the dealer and see if they can find it for you....
