Just seen your reply Mark as I am still not getting thread notifications...
Well I had it working in my 2011 with both the car SIM and mobile phone and also in this 2014 with the same setup.
I use the car SIM to make/receive calls and Audi Online Services not my mobile.
I think a previous MMI software update enabled the choice of making calls via either the car SIM or mobile phone if that might make a difference?
My car had this option from the factory.
I'm guessing it has something to do with the complete ****-up that was my visit to Audi Northampton to update the MMI software.
They had the car for over half a day and when I drove it away I checked the versions and it was exactly the same as when it was when I drove it in so I turned around for them to have another go.
This time the maps had been updated (I wasn't bothered about that because I always use Google Earth) but the MMI software itself was still on the 2014 factory version.
They said they weren't prepared to update the MMI version despite them doing my 2011 pre-facelift when requested last year.
Odd then that my 2011 car had newer software than my 2014 facelift using the same dealer...
