I was working on an audi A5 all keys lost. I tried to read bcm2 with my vvdi key tool plus and soldering free adapter but key tool plus keeps telling me that failed to connect with the adapter. I correctly connected the adapter with DB15 cable. Don’t know why KTP still can’t connect to the adapter.
It’s my first time using bcm2 adapter with Keytool plus. I was able to read the bcm2 with same adapter but with the vvdi prog.
Check if the adapter is connected to the board properly.
If you look at where the pogos are supposed to go, line them up first before putting the side clips on it will work.
