Wonder if it was because I didn't do a full stop and did more of a roll and when I accelerated the transmission just got confused. It's the automatic dct by the way. Never happened before though, even with the roll stops. Also while I'm at it, I never did notice any difference in the transmission after the update earlier this year.
What likely happened is that the car disengaged the clutch as you came close to stopping, and at precisely the same time you tried to accelerate. The computer has to reengage the clutch before you can go anywhere, and by the time it was able to do so you likely were given it more throttle then desired, which is why it took off like it did.
I can repeat this "issue" in my car at will. I don't believe it's an actual problem with the car, rather you just need to make sure to time your stops so you are not attempting to accelerate when the car is almost stopped. Either give it just a bit more time to reengage the clutch after releasing the brake, or come to a complete stop before accelerating again. This is just something the DCT does, as it has clutches and not a torque converter. A traditional automatic would always stay in gear, and connected to the engine, allowing for such operation, whereas our gearbox does not.
