The Audi A3 does not have an MMI system. They are only present in A1, A4 upwards.
I'm assuming you have an RNSe installed in your car? How long have you had the Bluetooth and RNSe? Did you install it yourself? Seems like it hasn't been coded correctly.
Make sure that your contacts do not have any special characters in as this can sometimes throw things.
