What's the difference in the two?
How do i know what my 98 2.8L Quattro has?

 

never mind, i found out i have servotronic power steering.

 

Does it make a difference?

 

I don't know.

 

Just about all audi's have servotronic steering, its used on most of the german cars and volvo.
It does make a difference, it makes it easier to control the car, a servotronic system is speed variant. The slower you go the stronger the power assist is applied to the steering, it makes it more precise.

 

i think it is standard in the states
