Can you guys help out the guy below? I bet you can....

BTW, I got the Ross-Tech software and cable for my A8, you wouldn't believe
how you can troubleshoot the car, don't need to get past your PC. Fixed my
CC system by using the software and seeing what motor was bad....too cool.

The A8 is still absolutely awesome! Removed the badges (too cool), got the
windows tinted (light) and gonna get some xeons (www.hids4less.com).

Not on the list, hope all is well!
