Thanks for reaching out today and welcome to the Bose Community Forums.
I would love to assist you in getting this issue resolved, however, I really would need to know which specific SoundSports you have. You can use this page here to type in the serial number of your headphones. I believe that your VW Bluetooth may only receive audio signal, not send it, as this is most common in vehicles, but this will need to be confirmed by VW.
I very much look forward to your response.
