Bluetooth sign on dash but refusing to connect with iPhone

[Garygibbs]

Hi All! I'm a newbie! My 2017 A6 has been in at the main dealer, charged £154 and they couldn't diagnose the problem. They suggested another 2 hours at another £308 but with no guarantee of finding or fixing. I decided at this rate I could manage without hands free calls! Any thoughts? Thanks!
