subaru alarm gone quiet
 

gonna try and make this short . .
disconnected my battery about 8 months ago , stopped beeping when arming/disarming it , , recently hazards were flickering really fast , my alarm had been triggered but no sound/noise/siren.
rang local dealer,they told me that i've got to enter codes in my number pad,which is inside glove box. then i can have it loud or silent.
basically , when i disconnected the battery i reset the alarm to factory setting which is quiet . .
the dealer told me that these codes were in my manual but they aren't
i take it the codes are the same for all imprezas , obviously the 4 digit pin is different but the codes must be the same
the car is a my00 uk turbo classic
has anyone got these codes
thanks in advance
