Cruise control problems
I have an 1999 A6 Quatro, and the cruise control no longer works. I have heard this is a commmon problem, and I am hoping it has a common and easy fix. I have seen some references to a certait swtich but that is as much info as I have. Can anyone point me to some more info or do I need to take it into the shop?

RE: Cruise control problems
Manual says it should be fuse 11 but there is no fuse 11 in my car. The fuse slot has no backing so you can't even put a fuse there. I did just run a fuse tester down all the fuses though just to make sure none are out and they are all working fine.

RE: Cruise control problems
I had the same problem and after reseaching I figured it was probably the control unit, and it was.
I sent this little silver box ( says hella on it and it is behind the glove box ) to www.autoteck.com and they rebuilt it ( supposedly with state of the art components) for $120.00 with a 2yr warranty.
they advertise a 2-3 day turn aound but my took 2 wks due to THERE confusion.
ONCE AGAIN IT WORKS!!99 A6 2.8 BENG
