hi there have an alarm fault on my 4.0 p38 been to the garage and they cant find any fault codes? eka and immobiliser have alredy been disabled and also the ultrasonic sensor has been disabled. but alarm seems to set itself off whenever it feels like it and when you put key in it displays alarm trigger tamper fault? it even goes off when you lock doors seperatly and alarm led isnt lit. think maybe disabling alarm altogether would be better but will it still go off not sure? any clues thanks lee.
