I haven't had any issues yet since the other day, so I am just waiting for it to happen again and thinking it was a freak accident.
MrClean: did yours come out of the problem, or did you have to get it towed in to the shop?
It was weird.
The very first time it happened, my wife was driving. The car went into safe mode, which is basically neutral. She coasted to the side of the road and turned the car off for a moment then restarted it to find the car operating normally. She gingerly drove the car home without issue. Took in to dealer, flashed DCU, sent us on our way.
The second time it happened, I was driving to work on the freeway, as I was exiting (about 50 mph) the car went into safe mode (neutral) and I coasted to a stop on the off ramp with no where to pull off. So, I ended up in the way of traffic and several attempts to "reset" the DSG, as my wife did, failed. I ended up calling Audi Roadside for a tow (and the police because of the unsafe situation of a stalled car on a blind off ramp to the hwy). Car was flat bedded to the dealer, two days of trouble shooting, one reflash sent on our way.
The third time it happened, I was driving to work (avoiding the hwy b/c I no longer had confidence in the car). I was driving 45 mph went into safe mode again, coasted into a parking lot, called Audi Roadside again. Said 45 min response time. I let the car sit for 2-3 minutes, then restarted the car and it work. However, the car did the safe mode at least 4 more times in 5 miles; luckily I was able to pull off the road safely each time. By the time I got to the dealer, I was fuming!
I called Audi Customer Care and told them to keep the car! I then contacted my salesman and he worked out a deal for me on an Avant, but not before I had to drive the TT again to have it do it again!
Once Audi replaced the DCU (DSG control unit), I was told by my salesman the car was test driven extensively without issue. The car was certified and resold to someone and did not experience the problem again, as I was told.
I broke a cardinal rule of mine with this car, NEVER BUY THE FIRST YEAR OF ANY NEW CAR/TECHNOLOGY!
