Suggestion

in my case of vag can pro clone i have problem with bad soldering... i did check all the soldering and fix what it seems to be bad or poor soldering. After this i have no problem connecting to all of controlers on my car.

 

here are pictures of my VCP clone... at this point all works:

Finally.

ok, I see what's wrong, pin 1 to 3 on my board are not soldered and pin 9 to 13 on the other side are not soldered, I'll get VCP to work and let you know how I got on, cheers.

 

Good luck.
