Just accepted delivery on new A6 2.7T 6 spd MT. I have less than 400miles on vehicle.Car seems to run fine, but at idle it is not smooth; enough so that even the tach needle fluctuates slightly. There doesn't seem to be a miss, more like a hot cam in the muscle cars of the 70's. Irregular idle is present even when engine is warm. Amount of valve/tappet/injector noise from under the hood also surprised me. You don't hear it in the car. Before I go to the dealer, the car is quite new, I hoped to get some feedback from the newsgroup if this noise and idle is to be expected.
Thank you
