I have a 1998 A4 2.8 Quattro and I am having hesitation problems but only at highway speeds. It is only happening after slowing down and trying to accelerate up to speed again. The best way for me to describe this hesitation is that the car feels like it is stuttering and it also feels as if we are driving on a grooved road(feels bumpy). The car accelerates fine from a stand still. I had a mechanic at a STS Tire Center tell me I need to bring the car back to Audi because they need to "reset the computer"? Anyone ever hear of such a thing? I hope he is right because I can't deal with a major transmission problem. Any feedback would be greatly welcomed!
Thanks in advance, John
