So far I was able to disconnect that module so every thing drives as it should and I was able to leave fuse # 9 in place since the signal won't be operable anymore to that output of the alarm since the module is disconnected. The car can be driven in the mean time and I am now on the look out for a module to buy so I can replace it. I took the foam insert out and will let it dry for a few days and see how that turns out.

I am facing the same issue. I have spent 2 days reading through the forum. I must say this is an amazing source with very knowledgable and experienced members. My alarm has been going off randomly but I have been able to silence it by unlocking car through key fob. It happens frequently (3-4 times in an hour). Lately, I just unlock the car and leave the key in the ignition (at OFF) so the doors stay unlocked and alarm remains disarmed (car stays parked in locked garage). This has temporarily solved my alarm siren problem. Today I locked the car and 10 minutes later the alarm went off and it was extremely loud as always but key fob could not silence it. It completed it cycle and temporarily silenced itself. The siren was continuous but I could hear strange sounds coming from the siren as if the battery is running out or electricity sound effect. At the moment I have fuse #9 removed and key in ignition to keep car unlocked and alarm disarmed. I have a booking with a dealer in 6 days but I want to keep the alarm from going off. So far fuse#9 and unlocked car have kept it silenced but I am not sure if it is going to keep it off for a week. I know disconnecting the battery will not help.

Right now I am requesting some help as to whether I should remove the Alarm Siren all together or Central Locking Pump Module? Which is an easier job and guarantees no alarm siren? Or fuse 9 removed and car unlocked will keep it off? Any help is appreciated. I am already grateful for all the members who have posted helpful information on this thread.
