1998 Audi A6 6 cyl All Wheel Drive Automatic 170000 miles
I also have a 1998 A6 and the cruise control is not working. I know where the c/c mod. Is, but I can't seem to find any diagnostic info. I have a Bently repair manual, but it doesn't have much on diagnostics. I have a Snap-on Solas pro but I don't see any thing on c/c. Is there a way to diagnose without parts replacing?
