Problem:

Hi, I need engineering help, the allscanner vxdiag benz c6 has stopped working.
After vci firmware update.
Xentry will not recognized

Solution:

As the error indicated that the firmware version of the Xentry VCI is too new.

Result:

I have fixed it, lots of re-configuring and rolling back the vci drivers.
It is almost the same as installing new hard drive.

1. Mercedes benz partition. You have to update vci firmware vx manager.

Reboot.

Start mercedes vci manager and select the proper xentry software version mine is 2019.7.

Then the mercedes benz c6 vci and xentry will communicate.
