My 2009 A6 MMI intermittently went on/of, then off for several days, then died. Problem was a short in the wiring harness, which eventually fried the MMI computer. The dealer had it for 2 months before finding the problem (the tech snagged a wire behind the dash on his finger and the "dead" MMI came on!). God know how many hours they spent before they found that, then it needed a new MMI computer. They charged me $1800 all together, an insane bargain just for the tech time. Hope yours is less of an issue...
