I have a 1998 Disco V8 auto which has an additional Land Rover Engine Immobiliser using a Green fob and Gold Fob. The car has been standing for the best part of a year and now that I want to get it running again, there is no response from the Additional immobiliser. The instructions say to hold the Green fob above the steering column cowl until I hear 2 bleeps but of course nothing happens. Anyone have any idea on how to bring it back to life? I obviously have no feed to the starter or the fuel pump. Thanks for any help.
