Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This bulletin provides additoinal information to assist in determining the energy content of lithium-ion high-voltage batteries.

At times Vehicle suddenly loses power and displays “transmission malfunction:you may continue driving” but then fails to accelerate to or maintain highway speeds. Other times when vehicle is stopped in traffic the transmission delays engaging when pressing in the accelerator and thus causes an unexpected delay to movement or if on an incline will roll backwards.
Transmission shifts strange when cold. Acts like it loosed power every shift. Strange clunking as well on slow speeds or number to number traffic. Sometimes it scared me that it will jump forward and hit the car on front of me.
The problems started by a warning on my display saying to pull over gear box or transmission failure. You have seconds to pull over before the car no longer functions. Even though you are in gear all that happens is the engine revs and you go no where. My car has only 38,500 miles on it and is out of warranty by a couple of months. I had the car tuned adding somewhere around 100 hp 6,000 miles…
Dsg issues. Clunking when downshifting into 1st / 2nd when stopping. Shift hesitation on upshift as well .
Transmission error, at first says you can continue driving in limp mode but shortly after says put car into park. Got stuck on the road several times in a single 10 mile trip.
Transmission shifts harshly and makes noise during shifts. Was told the mechatronics need replacement. Sometimes when accelerating the car will jolt as if it it loses power momentarily. When merging into traffic in could be dangerous.
Transmission warning indicator on, shift hard
This vehicle is known for having a faulty mechatronics unit. The mechatronics unit does not work correctly, and causes jerking and instability to the dsg transmission. I have almost rear ended other vehicles at red lights because the transmission will jerk forward unexpectedly and lunge me forward toward the vehicle ahead. This is not only an issue that a prestigious name like Audi should not…
