Hi my name is***** am a diagnostic technician and look forward to working with you.The alarm siren module is located behind the drivers side front wing, it is under the plastic wheel arch liner fixed to the chassis on a bracket. The siren will be fixed using a security bolt so will require either cutting or drilling the head off the bolt. The siren module will then need to be programmed to the car, the modules are coded from the factory, when using a second hand part, the coding needs to be removed and re-programmed. This can be carried out at a main dealer or specialist for around £120I hope I’ve provided the information you were seeking.
