Here are two methods usually adopted by BMW owners with BMW ICOM A2 WinKFP.

First method

to lock the ICOM to Connection Mode: STATIC_IP and then use iTool Radar by Nubix to locate it on the LAN.

Second method

but that you will need the password of ICOM, but as no one brings out the password, you can forget this possibility.

only possibility is more like you’ve already described the ICOM itools with radar and lock.
in the Ediabas.ini you have to change something
Interface: REMOTE
and host the ip the ICOM have.
ICOM you can put on STATIC_IP with a file called
USER.settings(open it with editor)

ConnectionMode = STATIC_IP
Ip = 192.168.68.40
Netmask = 255.255.255.0
Gateway = 192.168.68.1

and a file which is called user.settings.log must remain empty.
The ICOM describes this file automatically.

these two files on a USB stick(USB2.0) into the BMW ICOM usb port
light of ICOM will turn on.
ICOM must properly afterwards user.settings.log have described themselves.
