I purchased my HEX-V2 last October or so. It would not communicate with any control modules on my "new" 2004 Touareg. However, it worked fine with my 2017 Golf Alltrack, so I figured the Touareg had some issues. After chasing wiring on the car for a while, I finally broke down and brought it in to a shop. They plugged in their VCDS and it worked just fine. So, after troubleshooting the car for a while, it seems like I actually have something going on with my interface.
What do I need to do in order to get my interface working on the Touareg?
Some relevant info:
- VCDS is updated to version 20.4
- I checked for interface updates through interface config, it says I'm up to date
- The shop used their interface with my VCDS software on my laptop, and it connected to all control modules without issue (I think it was a HEX-NET, but not sure, they said it was a few years old)
- When connected to the Touareg, the Port Test shows K1 and K2 as both "OK"
- I tried "Force K-Line on Engine", "Bypass CAN Init", "KWP-1281", "KWP-2000", all to no avail.
- With Touareg connected, it does not ask if I want to add the VIN like it does on my Alltrack
