I had the same problem after I got my 15K service back in April. I brought the car back and they said they cranked it up to the max but it was still too low. I started researching online and found out that I was not the only one with this problem. I even forwarded this link to the dealer. I told them that Audi must have a solution for this because it is not an isolated issue. Thankfully, there is a solution and my bluetooth was fixed last week! Audi recently sent out TSB (technical service bulletin) #2018475/2 which is apparently a "radio adaption" as stated on my invoice. My bluetooth is now back to normal. You all should contact your local Audi dealer and reference this TSB so that your bluetooth issues can be fixed.
