Maybe you switched ISTA+ to BMW only mode? Else try with INPA or tool32 and check if these can connect.

All other programs like Ncs also no connection. On other BMW direct connection with al programs? Very stange.

Do you run "easyconnect" or "easykfp" and choice "STD:OBD" to connect?

I use Ediabas-Konfigurator. I think there is something confusing the K-line from the car?

I have said several times: On other BMW direct connection, so the problem is not on my laptop!

Hello, use a multimeter to measure in the OBD socket of the car:
- pin 4 (ground) and pin 7 (K-line)
- pin 4 (ground) and pin 8 (K-line)

you should see in both readings a value greater than 11V.
Although your Snap on tool works it probably communicates with only a few modules, I would try to use the Snap on to communicate with the instrument cluster then check with either Inpa KDCAN or ICOM to see if you can use NcsExpert or Inpa software to communicate with the instrument cluster.

cheers!
