I have a 2016 Caravelle, even if I enable the functions (Module 09, Byte 05) they do not activate, only optical confirmation. My van has no siren anti-theft system but the sound should be played with just the horn, right? What am I doing wrong?
Yesterday I talked to a Vw technician, he said that on some models (year 2016 left hand drive) if you consult the control unit it makes you read two options: horn and siren but only the siren works (with anti-theft system installed), volkswagen mysteries.
So to make some noise I have to install the alarm.
