Alarm system on my 99.5 a4
My alarm system stopped working. I can still lock my car using they key and it will lock the whole car which means that the vacuum pump is working, but it will no longer turns on the alarm like it use to before. I checked the fuse box but everything seems to be good in there. Any idea on what could be wrong with the alarm?

I just noticed something interesting. My car locks fine from inside and from the drivers door lock, but when i try locking it from the truck it wont lock the car, everything stay open, is there maybe a sensor in the trunk and its not detecting the trunk being closed?
edit: it use to lock just fine from the trunk aswell.

Check the codes, if there's nothing go through the measuring blocks one by one to test the function of the door/hood/trunk switches. If that fails it could be a wiring issue inside the trunk, so you'd have to pull the liner and inspect the lock cylinder. I'm not too familiar with the central locking module, but if there's a way to see whether you have a lock button pressed or not, that would be a good thing to check too.
