I bought a HEX-V2 and installed it on my laptop, it worked excellent as soon as I plugged it into my 2006 VW Jetta TDI and I was able to check and clear codes. the next day I used it again to set the cam timing and everything worked as it should once again, About a week later I installed a Android touch screen head unit. the head unit came fit for my car, wiring harness and all, complete plug and play unit. When I was done the install, I had some DTC codes so I plugged the HEX-V2 in again but this time I cant get anything to work. VCDS loads fine, I can choose what area I want to go into like Control Modules for example but when I click on anything in the section, the loading icon appears for a few seconds and then disappears. I then tried to register my device and could get nothing but empty boxes in VCIConfig. in VCDS when I click on options and test, HEX-V2 tests okay. I read the thread about the CAN + and CAN - wires on the head unit shouldn't be connected to anything but that was after I Had tried to clear the codes after the head unit install. those two wires are connected from the factory wiring harness to the head unit. I cut them to see if it would make a difference but it didn't and the head unit does not turn on and off properly with the key with them cut.

Where did you buy this "HEX-V2"?

Notice that VCDS doesn't see a HEX-V2, but rather a HEX-USB+CAN. That's very common with what we call "Faux-V2" pirate clones.

Post a picture of the "HEX-V2" itself please.

Okay I will do that. How do you identify it as a fake? Is it just because of where I bought it or it there a physical identification?

Where you bought it is just one factor, but there are a number of things about that interface that are visuallu dead give-aways that it's a clone/pirate fake. Sorry, I'm not going to spell out what they are; that would make it too easy to make more realistic-looking ones. Bottom line: If you want a legitimate VCDS system, buy it from a trusted source rather than someplace that has deals that are too good to be true.
