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?
On this car, it shows DoIP information
It shows nothing on another Mercedes.
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.
