Staying current with the latest diagnostic software is crucial for any auto repair shop specializing in Mercedes-Benz vehicles. The XENTRY Diagnosis system, renowned for its comprehensive diagnostic capabilities, requires regular updates to maintain peak performance and access the latest vehicle information. This guide provides a detailed overview of the Xentry Diagnosis Update process, including the XENTRY Update Service and the benefits of using a Retail Data Storage device.
Streamlining Your XENTRY Diagnosis Update Process with XENTRY Update Service
The XENTRY Update Service delivers essential updates, including ECU and flash software, directly to your workshop via an online connection. This service replaces the older “Regio DVD” and “Digital Operator’s Manuals” by providing a centralized, online platform for all necessary updates, ensuring your diagnostic system always has the most current information. There are two primary options for utilizing the XENTRY Update Service:
- XENTRY Update Service with Retail Data Storage (Recommended): This option leverages a dedicated network storage device to optimize the update process.
- XENTRY Update Service without Retail Data Storage: While functional, this option presents several drawbacks, particularly for workshops with multiple diagnostic systems.
The increasing complexity of modern vehicles necessitates larger data volumes for updates. The Retail Data Storage 2, featuring an 18-terabyte hard drive and significantly faster data transfer speeds, addresses this challenge effectively.

Benefits of Using Retail Data Storage for XENTRY Diagnosis Update
The XENTRY Update Service with Retail Data Storage offers significant advantages, including:
- Automated Updates: New releases and add-ons are automatically downloaded to your Retail Data Storage within 48 hours of publication and then distributed to your XENTRY diagnostic devices. This automated process minimizes manual intervention and ensures consistent updates across all systems.
- Reduced Downtime: Background download and installation processes minimize disruption to your workflow, reducing update time to approximately five minutes per device.
- Customizable Download Schedules: Define specific download times, such as during off-hours, to minimize impact on workshop operations.
- Efficient Bandwidth Utilization: With Retail Data Storage, updates are downloaded only once and then distributed to multiple diagnostic devices, significantly reducing internet bandwidth consumption.
XENTRY Diagnosis Update Without Retail Data Storage: Considerations
Opting for the XENTRY Update Service without Retail Data Storage can lead to:
- Redundant Downloads: Each diagnostic device must download updates individually, consuming more bandwidth and time.
- Increased Workshop Downtime: Longer download times can significantly impact productivity, especially for frequent users.
This option is generally suitable only for workshops with one or two infrequently used diagnostic systems. For optimal efficiency, the XENTRY Update Service with Retail Data Storage is strongly recommended.
Optimizing Control Unit Programming with the USB to LAN Adapter
Larger control unit software files in newer vehicle models require longer transfer times via the OBD port, which is limited to 100 Mbit/s. The USB to LAN Adapter offers a significant improvement, enabling data transfer speeds of up to 300 Mbit/s via the vehicle’s USB-C port. This faster transfer speed drastically reduces programming time, enhancing workshop efficiency.
Key Advantages of the USB to LAN Adapter:
- Faster Data Transfer: Experience up to three times faster data transfer speeds compared to traditional OBD programming.
- Stable Connection: The cabled connection ensures a stable and reliable data transfer, minimizing interruptions.
Requirements for Using the USB to LAN Adapter:
- Retail Data Storage in the same network as the adapter and diagnostic device.
- Cat5e or higher LAN cable.
- Up-to-date XENTRY Diagnosis Software and compatible VCI.
- Compatible vehicle models and control units (currently 214 (E-Class), 236 (CLE-Class), and head unit).
