OBDEleven Problem with Audi A4 B6 8E

Hello together I googled eeeewig and find nothing to my mistake. I bought the OBDEleven nextgen. Connected with Bluetooth and plugged in the car on the OBD plug. Right at the beginning when connecting comes the message – “Make sure that the ignition is switched on”. The ignition is switched on! Unfortunately I can only go further and choose my car manually. By not detecting the ignition I can also search no ECUs or only 1-2 are found. It seems that the plug really lacks the ignition. What I don’t understand, however, because with VCDS everything works like it should. Only exception recently – I can’t access the control unit of my original. Autoradios what I used to be able to do with VCDS. However, the radio funts and is also displayed on the FIS. I looked at the pin placement on the OBD plug. Pin 1 to 16 Occupancy 1 blue black 4 brown 5 brown 7 green red 15 green blue 16 red brown All others are not connected. I don’t have a CAN connection but I don’t have a J1850 bus, just K-line and L-line. Could it be that my OBDEleven doesn’t work? On other vehicles like Golf 5 and Scirroco it works quite normal. But I’ve already seen youtube videos where all the control units are read out on the Audi A4 8E B6 and the car is also in the list of OBDEleven. Ask for help – don’t know any more. thank you Christian
