I have an A4 1997 quattro with 110000 miles and when I leave my driveway or anywhere if I turn hard in either direction the car has this weird vibration until the car picks up speed or I start to straighten out my wheel. only does this from a start not when under speed. T

 

yeah, we ALL have that to deal with. It's a full-time AWD-thing, I think... You learn to live with it, eventually, ro, not make sharp turns from a stand-still

 

For the most part as you make a tight turn at low speed one wheel has to turn further that the other ( the one on the outside of the turn). Because both front wheels receive power one has to give up the power (often known as clutch packs) and it results in that vibration you mentioned.
