What do I Do???
My wife bought a new Battery for our 2006 A6. The company that replaced it constantly had power to the car while replacing. When she left the place the MMI Screen read "processing" then clicked on and off a couple of times, the next Day It would not turn on. A friend of ours has a Stereo shop he checked it over all Fuses are fine power to everything Radio, Nav, CD. Said he was confused. Took it back to the Dealer same thing The MMI screen comes on for a few seconds and shuts off the lights on the console turn on very dim for a second then off and you can hear poping in the Speakers. WHAT THE HELL DO I DO??
