Problem:
The Xhorse VVDI Key Tool Plus just gave me an error when I was connecting the pad to Audi BCM2 Solder-free Adapter.
It says: "12V Unconnect or Adapter Connect Line Error".
I've tried another 12V cable, but it still doesn't work.
What's the problem? please advice.
Solution
The error means there must be something wrong with connection or power line. Please ensure to check connection diagram before programming each time.
In this case, it requires to use the DB15 Cable(Key Tool Plus accessories) to connect with Audi BCM2 Adapter. Please do not connect other unknown cables. That's the reason.
Thanks to Xhorsestore.co.uk, problem was solved!
If you have same problem, just check the connection again carefully.
