VXDIAG VCX SE Don’t Show Information in DoIP Config?

Problem:

I have a question with vxdiag vcx se benz doip scanner. I always turn on the DoIP switch before connecting to a Mercedes. Sometimes it does show DoIP and VIN information in DoIP Config interface, sometimes does not. see images comparison below.  Any idea how to fix it?

Vxdiag Vcx Doip Info 1

On this car, it shows DoIP information

Vxdiag Vcx Doip Info 2

It shows nothing on another Mercedes.

 

Solution:

Only when you diagnose DoIP protocol Mercedes Benz, you are required to turn on the DoIP switch.  Otherwise, it is not necessary and it won’t display DoIP information.
