Il supporto di Obdeleven mi ha risposto:

"YOU GIT THE WRONG INSTRUCTION FOR THIS FUNCTION. FIND PROPER INSTRUCTIONS SPECIFICALLY FOR YOUR VEHICLE MODEL.
THE INSTRUCTION YOU HAVE PROVIDED ARE FOR THE UDS PROTOCOL. THIS CONTROL UNIT YOU HAVE IS EQUIPED WITH AN OLDER KWP PROTOCOL, WHICH HAS CHANNELS IN IT.
YOU WILL NEED TO DO THE RESEARCH BEFORE DOING ANYTHING. I STRONGLY RECOMENDED YOU DO NOT EXPERIMENT WITH THE FUNCTION IF YOU DO NOT KNOW WHAT YOU ARE DOING TO YOUR VEHICLE "

Deduco che non ho speranze...
Mi spiace molto. mi sarebbe piaciuto avere gli abbaglianti automatici sulla mia auto...
