Fixed! VVDI Audi BCM Adapter "12V power not connected" Error
Issue:
Trying to add key for Audi with encrypted BCM2, using VVDI Audi Solder-free Adapter. I have connected 12V power but why my Key Tool Plus keeps saying "12V power not connected or incorrect adapter connection"?
How to Check?
1)If the power is 12V, 3-5A
2)If the connection is correct
The customer's power supply is correct (12V, 4A), then we check the connection and find the
Reason:
Key Tool Plus is connected via left DB15 port not DB25 port.

Besides, the required cable is in
Key Tool Plus package, not this one in
VVDI BCM Adapter package (the cable that doesn't match is for
VVDI PROG).
