About a week and a half ago I bought my first audi, a 2010 A4 quattro 2.0t. The first few days it was running absolutely great but a couple days ago i started having this problem. Whenever I accelerate hard the car jumps then accelerates then jumps a couple more times then accelerates more. They are very short/quick stutters and are somewhat subtle in the sense that is is not completely jerking me around but it is definitely noticeable. The first time it happened it was just one slight stutter but now it is several. I have noticed that it does it when accelerating from low rpm if im on the highway trying to pass but it also does it if im taking off from a dead stop. I have noticed that it doesnt happen though when the car is cold. It usually only happens when it gets up to optimal operating temperature. I think there might be some boost lost from the turbo but i might just be tricking my brain into thinking im not going as fast. Anyway. There are no codes or lights that show up on the dash and i dont know what is wrong. If anyone has ANY ideas or suggestions PLEASE let me know, it would be greatly appreciated.
