If I understand correctly, your BL double honk on exit with key was already disabled and you believe they do not come from factory that way. If that is correct the explanation is the 25 sync 4 has an option to turn of the double honk. I found it in the settings. Someone at the dealer probably turned it off. If I misunderstood then sorry for the response.I just received my 25 BL SAS and the double honk is disengaged. Can't from factory that way. I haven't done any of the mods yet. Are all the mods/changes wiring for the 25s? Glad I found out about the change with having to remove eco to add sport
