Pulling the fuse might not help at all. The following is a cut & paste from a posting by senior member Willy:
"The car communicates with the siren module by means of a serial link. Even when fuse 38 is removed and the car is shut down, this continues, it can be heard as a ticking sound. Perhaps this causes the battery to run down over time. I had a faulty siren module while on holiday, to be double sure I had the connector at the module unpluggedd (still is that way, haven't decided wether I will replace the siren.
