I have a 1999 A6 avant and I'm having cruise and tiptronic problems. The cruise does not work at all, not even intermitently. The tiptronic doesn't even register on the in dash display when its put over into the manual mode. Now when I cheked the fuse that supposedly controls both there is no fuse in the spot and it will not take a fuse. I saw the previous fix for the cruise, but am wondering if these two are related, and any experience anyone has had previous. Let me know
