    I know that this can be really frustrating.
    Did you change the coding on the HVAC or Telephone modules?
    Do you have an old scan to compare?

    It is haha and to answer your question i have never changed the coding on anything as not too sure whats what with it if that makes sense. And i have a scan that a guy did and he also couldnt pick up the bluetooth.. i will double check soon and upload the first original scan that i had done.

    Maybe 1 :
    The problem is in the voice control module and like Uwe said there is a bug in VCDS which won't let you communicate with Telephone module.

    Maybe 2:
    The problem is (also) in the voice control and that problem is causing the lack of communication with telephone module.

    I don't know if this can be done. But worth a try.
    Try to disconnect the voice control module (not sure if you already know where it is!) and see if with it disconnected you can communicate with telephone.

    Also, you can try the inverse:
    Try to disconnect the telephone and see if with it disconnected the voice control error can be erased.

    I don't understand why this error is thrown in HVAC (and also in Steering wheel)!

    Any ideas?

    Is there a way to sort out the bug in vcds? I dont actually know where the voice control module is to be honest. Do you happen to know.
    I have tried with the bluetooth module disconnected to erase rhe vlice control fault but it doesnt work :/
    Thanks for your quick replies too vasco 👍

    Hi. I also don't have any clue where the voice control module is.
    Are you sure that the voice control module is not the telephone module?

    Language input control unit -J507- is a separate module. Usually next to the telephone/telematics control unit under the front seat. In VCDS it should be at 0x66, but does not appear in your autoscan?? Check fuses, water ingress. The fault was logged in 2015, has a previous owner been messing?

    Thanks for the reply matty.. looking at that picture.. i dont have that other box next to my bluetooth module. And no one else has messed with my car i.e with vcds however the 2015 is probably when it stopped working on me..
    No signs of any water ingress either so perhaps it may all be linked in to my bluetooth module?
