Failed to Open 2024 MB SD C4/M6 Xentry Software Solution

 Some users have reported that the MB SD C4 DoIP/Super MB Pro M6 Xentry software (purchased through internal channels) suddenly stopped working on April 1st, 2025. After entering the usual username (Xentry) and password (88888), the program fails to open.

This issue affects different versions of Xentry XDOS OpenShell, 2024.03, 2024.09, 2023.09 etc.

This issue affects specific Mercedes-Benz diagnostic tools:

• MB SD C4 DoIP
• MB SD C5 
• Super MB Pro M6+/M6

 

Note: This issue does not affect users with VXDIAG devices running different software.

 

 

Solution

For C4 and M6 devices where the Mercedes software fails to log in, the offline config file was expired. Follow these steps to solve the problem:

1. Locate the Replacement Files:
   • Download the offline configuration files (offline_properties).
2. Replace the First File:
   • Navigate to: C:\ProgramData\Mercedes-Benz\config\XD_DT
   • Replace the existing file with the new one.
3. Replace the Second File:
   • Navigate to: C:\ProgramData\Mercedes-Benz\config\XD_MB
   • Replace the existing file with the new one.

Important: Both files must be replaced—skipping either one may not resolve the issue.
