      Hey everyone!

      I have a 2007 A6 avant. Gonna get to the point. My MMI started hiccuping every once in a while, turning off and then on or speakers would pop and audio would go out for a second. Then all of a sudden everything went out and stopped working. Im posting the vagcom results at the end here. But i have tried to diagnose on my own. I bought a loop so that i could eliminate components to see if any particular component died on me and is causing the issue. I took the back panel out and tested the amp, radio unit, satelite radio, and dvd drive. The only one i saw results from was disconnecting the radio controller. MMI would start up and work but the control knob and buttons by the shifter would not be responsive and the system would shut back down after 5 seconds. I would be appreciative if someone could point me in the right direction. Thanks
