Hi everyone, I'm new here and I think am having issues with my VCDS Vagcom unit... I have the full licensed version of VCDS version 15.7 and a Ross-Tech KII USB interface. My car is a '99 Audi A4 1.8t Quattro Avant (prefacelift). My cruise control has never worked since I purchased the car like 6 years ago. I'm trying to run diagnostics to find what the problem is. I used this guide - Waks Wide Web
However, in the 4 fields all I see on my rig is N/A. Other groups I can get readings in all of the fields, but a lot of them, including 066 all 4 just say N/A. Anyone know what the issue is?

Thanks
