I recently had the Alternator replaced and I now feel a slight vibration in the wheel and in break pedal while both idle and moving. This vibration was not there previously.. No CE lights or SRVC lights are on etc. 

I drive a 2011 C300 Luxury. 

Any help would be appreciated.

check the belts ASAP!  Happened to me too few months back. you should put the belts on backwards on one of the pulleys and I felt the same vibrations as you. I'm not sure how but it destroyed the new alternator in a matter of a day leaving me stranded on the roadside.

Could be a weak tensioner spring now allowing the belt to slip a little causing a vibration . Just start the engine and look at the tensioner and see if its bouncing back and forth. Usually little movement. A bad idler bearing causing resistance . Or possibly even the new alternator. Maybe a bent or loose pully?
