MyAudi access - access to some online info should be working on your unit (A6/4G) if it's MMI 3GP and have SIM slot.
For the traffic online cant tell you much as here in Bulgaria we don't use it as it's useless. If your unit have SIM slot you can ask your local Audi dealer as there is some fee if the vehicle is more than 3 years old.
Currently all other solutions are not working, but i believe that the fee is no more than 50-80E per year which i believe is not so much money :)
As for the help - i will try to help you with what i know and can but my time is limited .... this is just a hobby for me and as it turned out there are some people that i've helped and then they spit you in the face.
Cheers.
