2005 Audi A4 Quattro Question: Vibrating Steering Wheel
Have the tires balanced first and tell them about the vibration as you might have a bent wheel or warped brake rotor - Valleyautotech
most audi dealers and good tire shops use a "road force" balance machine which can pick up tire related issues that dont show up from balancing. a bent rim or tire problem are most likely but have tierods, brakes, etc checked. - some guy
Our technicians recommend having the constant velocity (CV) boots and CV joints inspected at each service. Servicing torn CV boots early can prevent the need to replace the CV half shaft or CV joint.
