Battery Drain ed after 2 days

I have a jaguar s-type 2005 after two days it will not start…New battery. after 60 minutes unlock car the alarm goes on if i open the door.
when it is locked all the light around the car is flashing now and then -very nice indeed.
If I remove the fuse inside car for front electronic module it stop and no drining battery .
I have remove this module and let a electronic expert look on it - seems good and no moister.
The car is working perfect all the time after start.
Does anyone knoww anything about this -cable problem - other sugestions ?
