Can anyone help please, my 2004, 2.7 S type has a problem which seems unfixable, every 30 mins without fail the lights flash whether the car is locked or not, also if the car is unlocked and not opened for 20 mins or so the alarm goes off when the door is opened, this results in the battery discharging after 5 or 6 days, two visits to separate workshops for diagnostics have failed to reveal anything, been trying to resolve this for months, can anyone help please
Regards
Andy
