only_AUDI_2

Hello all, i have recently bought Audi A4 2009year S-line and the MMI was damaged, so I've replaced it with MMI from Audi A6 2006 year, after few days of playing with codings and adaptations I got it to work perfectly, except one thing, i can find my Telephone, it used to connect to Audi UHV 5071 , but now even in VAG-COM i can't connect to it, any suggestions how to fix this?
