I cannot read MEVD17.2.5 DFlash and Pflash with my newly purchased VVDI Bosch Ecu Adapter. I am using the adapter for the first time. Ecu is solid and I can read ISN with cgdi bmw. I need your experience in this matter. 
The PC date is correct. The pc is connected to the internet. VVDI Prog adapter is plugged in. Pin connection is correct.

VVDI Prog version 5.2.4

You must connect like this picture and should works:

VVDI connection difference is ground only. I tried this link. Not working. With the schema you shared, cgdi reads bmw ISN. Cgdi Bmw doesn't allow to save eeprom. I need to save eeprom without opening ecu.

With this connection PCMFLASH read and write D & P Flash so connection is ok. Maybe somethings wrong with yours adapter.

With this link, cgdi bmw can read and write. No problem. Vvdi is not reading with Prog Adapter. I think the adapter that came with is faulty.
