peddle vibration/grinding?
 

Hello everyone, I just got a nice B6 S4 tip. I have only had it for just under a week, but I had a question. Some times while driving, more so coasting. I can kind of feel a vibration in the gas peddle and and very slightly in the steering wheel. Its almost a combination of a grind and vibration. It sort of feels like the front brakes are just barely trying to grab. Any thought?

Other then that I love the car. Only other issue is the one with the radio volume going in and out, but I have the TSB here to take to my dealer for that one.

Thanks in advance.
