You should explain exactly what happens if you want proper help, is that with engine running or ignition off and neutral how from gearbox or transfer box ?
if the engine is running and select neutral there is a continuous sound from the alarm horn, but only in neutral.
i try a few things and when the ecu restart it was there.
i play the orginal software on the ecu and it was gone
but i was interrested what it was. i accidentally change one option
-Motronic
- VALEO BCU
-SETTINGS
-TRANS-LOCK-WARN
´´Shift Interlock´´ must stand on ´´NONE´´
i change it to ´´SHIFT´´ and then it honks

Yes cos the shift interlock is part of the security system and it seems that the sounder is activated if the setting is like the interlock is there while it isnt or it's faulty
