For professionals in automotive diagnostics using Mercedes-Benz systems, the question of software and hardware compatibility is crucial. Many still rely on the Part D (C3) multiplexer for its robustness and reliability. However, as diagnostic software evolves, particularly with versions like Xentry Diagnostic Openshell XDOS 2016, understanding the limitations and optimal usage becomes essential. This article explores the compatibility of Xentry Xdos 2016 with the Part D C3 multiplexer, offering guidance for users seeking the best performance from their diagnostic setup.
While newer diagnostic interfaces like Part Z (Bosch VCI) have replaced Part D, the C3 multiplexer remains functional, especially with older software versions. If you are considering using your C3 multiplexer with Xentry XDOS versions up to 2016, some adjustments might be necessary to ensure proper communication. One potential workaround involves modifying the toolkit.ini file, located within the SDconnect Toolkit directory.
By locating the toolkit.ini file, typically found in C:Program FilesMercedes-BenzSDconnect Toolkitbin or C:Program Files (x86)Mercedes-BenzSDconnect Toolkitbin, you can potentially enable your C3 multiplexer to be recognized. Within this file, find the line UseComPorts=. Here, you can specify the COM port number you intend to use for communication.
Furthermore, another line, SkipComPorts=all, needs modification. By adding a semicolon at the beginning of this line, ;SkipComPorts=all, you effectively comment out or disable this command, instructing the system to no longer skip all COM ports. This modification may allow SDnetControl to detect your C3 interface.

Modified line=
;SkipComPorts=allIt’s important to note that while this modification might facilitate interface detection, full functionality with Xentry XDOS 2016 is not guaranteed, especially for newer vehicles. Experiences suggest that Xentry versions up to 12/2015 are more reliably compatible with C3 multiplexers, with version 09/2014 often cited as the most stable and preferred choice.
While Xentry 05/2016 has been reported to function with Part D (C3) in some setups, it is generally considered the last version where this compatibility is reasonably achievable. Beyond this version, compatibility issues become more prevalent, particularly with vehicles requiring faster CAN bus communication protocols. For newer Mercedes-Benz models, Part D (C3) is not suitable due to these technological advancements in vehicle communication systems.
For specific tasks like offline coding, Xentry version 11/2012 is often recommended as a robust and reliable option when paired with a C3 multiplexer. This version strikes a balance between functionality and compatibility, especially for older vehicle models.
In conclusion, while Xentry XDOS 2016 and potentially even Xentry 05/2016 might be made to interface with a Part D (C3) multiplexer through system modifications, it is crucial to understand the limitations. For optimal and reliable diagnostics, particularly on newer vehicles, upgrading to a newer VCI is advisable. However, for users working on older Mercedes-Benz models, sticking with Xentry versions from 2015 and earlier, with a strong preference for Xentry 09/2014, remains a practical and efficient solution when using a Part D (C3) multiplexer.
