OK, I've had my RS6 for about two months. Picked it up from it's first owner with 13k miles. During hard acceleration in any gear, i get some hesitation in the engine. It is barely noticeable and inexperienced drivers do not even notice or feel it, but it is there and my local Audi dealer has confirmed it. They were unable to determine it's cause but are still researching it. Otherwise, they gave it a clean bill of health.
Anybody have any idea at all what it might be? Could this be a normal part of the acceleration.. the vehicle is still very fast.
The only option it is missing is the "loud" exhaust. It has the "quieter" exhaust.. every other option is on this vehicle.
