I have a Audi 2006 a4 Quattro and when u set the Cruz the Rpms will go up n down. And now its getting a bit worst so when u start it cold it will do the same untill it warms up.
Call me with info on what it could be, I was told it might be
a air idle intake motor/ air idle intake valve. But a few codes
pop up. Also when u take the gas cap off it does it. And
some miss fire codes. Jon Ebnet 218-750-3487
