I have a 2011 B8 S4. The dealer reflashed my transmission recently claiming it would fix the problem but I am still seeing a very jumpy modulation of the throttle especially in rush hour bumper to bumper traffic. I have tried both the comfort and dynamic setting as well as shifting manually (I have the 7spd dsg). It doesn't seem to be specific to any gear and it almost seems like the car gets into this mode where the throttle can't decide what to do after I have been in stop and start traffic. Makes the experience of driving the car even tougher in packed traffic. Any ideas or suggestions or has anyone else encountered it?
