Vehicle coding for control unit of the hands-free device Premium/ Bluetooth wanted

Good morning dear Phaetonians (and inside), maybe someone from the board can help me ? Problem: My Diva has an installed WLAN module ex factory, in which service checkbook glues the “letter stamp” front with all data (Wi-Fi SSID, password, IMEI, etc. pp ) but : in my AI the menu item does not exist despite rSAP phone coupling and working Google Earth. My friendly VW dealer has already replaced the ECU, but : the WLAN entry is missing (i I suspect that there is a bit to be set here somewhere in the depths of the ECUs that this fails. If someone could send a (anonymized) VCDS scan of his vehicle (if WLAN is installed) or one of the knowledgeers could possibly give a hint to the bit to be set, this would help me extremely well. My friendly VW dealer has already tried the problem for three days and doesn’t know any more … Thanks in advance & nice weekend e wishes Arndt
