ICV in A6? cause Unstable idle
 

Is the 2.8 30v A6 has ICV(Idle Control Valve)?

As the http://www.audiworld.com/tech/eng88.shtml, I am about to solve the problem

The 30v's dont have that valve. The idle is controlled by the throttle body. Sometimes an irregular idle can be fixed by removing the throttle body and cleaning it. Other times there is a vacuum leak causing the irregular idle. Sometimes adapting the throttle will smooth out the idle. Worst case scenario you need a new throttle body.
