VVDI Prog “DB25 Adapter not Connected” Solution


I have recently received my order (vvdi prog, vvdi bmw tool) installed the programs corresponding from website (vvdi bmw tool software no issue). but with vvdi prog software version 4.9.0 after install connected the programmer to laptop, driver was automatically installed and when I try to do a test it gives the error in the picture:


Check device…

12v power adapter unconnected

Initialization device…

DB25 adapter not connected


What should I do next?



Possible reason:

You did not connect the mcc cable with vvdi prog to test.



Yes, I did solve the problem, actualy it was not even a problem, it was a mistake made by me.

Try to test the unit without mcu cable attached.

Works fine thank you.
