Alarm Help - Going Mental

[jayster]

the Alarm keeps going off on my boxster

I lock the doors with the fob and roughly 3-5mins the alarm goes off

sometimes when i lock the car with the fob i get the 2 horn beep after - i have checked all compartments are closed etc
The battery is a Varta and been checked and thats fine, theres no water under passenger seat.
its going off at random times in the night - my neighbours must be impressed.

i took it to a local garage and put on a diagnostics machine - it found 9 faults

Heres the results, please if anyone can help im pulling my hairout
