Hello Q5ers. During a small road trip yesterday, my cruise control stopped working without any warning. I've checked to see if there was a fuse listed in the owner's manual, but didn't see anything. I haven't bought my VAG COM cable yet, is this something that's to require one? Or, am I going to have to take it to the "stealership"?

If some of you, like me, I rely on my C/C on a road trip. I really want to figure this out soon.

Thanks ahead of time.
