This pricing model allows workshops to choose a subscription duration that best suits their needs, from hourly access for occasional tasks to annual subscriptions for regular Mercedes-Benz servicing.
Diagnostic Capabilities of the XENTRY Pass Thru Device
The XENTRY Pass Thru EU software, when used with a compatible pass-thru device, provides a near-complete diagnostic scope for Mercedes-Benz vehicles. This includes a wide array of functionalities, closely mirroring the capabilities of more comprehensive diagnostic systems, but optimized for use with standard Pass Thru devices. Key diagnostic functions include:
- Quick Test and Functional Diagnosis: Enables rapid vehicle system scans and in-depth functional checks, although single-channel operation may result in longer runtimes compared to full-fledged systems.
- Basic Diagnosis: Accessible within the XENTRY Diagnosis environment, facilitating fundamental troubleshooting and analysis.
- Commissioning (Flashing, Coding, and Parameterization): Allows for control unit programming, software updates, and configuration adjustments essential for modern vehicle repair and maintenance.
- Fault Memory Management: Reading and clearing diagnostic trouble codes (DTCs) to pinpoint and resolve vehicle issues effectively.
- Guided and Functional Diagnosis: Step-by-step instructions and tests to aid technicians in complex diagnostic procedures and system analysis.
- DAS4 Services: Access to specific diagnostic and service functions relevant to Mercedes-Benz vehicles.
It’s important to note that while the XENTRY Pass Thru device offers extensive diagnostic coverage, some technical limitations are inherent due to the nature of Pass Thru devices. These primarily relate to speed and advanced multi-channel functionalities available in dedicated dealer tools.
Diagnosis is supported for:
- All passenger car model series certified to Euro 5 and 6 standards (Mercedes-Benz and smart). Note the DoIP considerations below.
- All van model series certified to Euro 5 and 6 standards (Mercedes-Benz). Again, see the DoIP note below.
- All purely Battery Electric Vehicles (BEVs) from Mercedes-Benz. Refer to the DoIP information for these models as well.
- XENTRY Flash capability is available across all Euro 5 and 6 certified model series, including BEVs.
- Symptom-based processing using standardized diagnostic symptoms for efficient troubleshooting.
- Diagnosis over IP (DoIP) is generally supported if the chosen Pass Thru device is DoIP compatible. However, if the Pass Thru device lacks DoIP support, flashing the Headunit and Instrument Cluster may not be possible for current PC and Van model series up to model series 206 and 223.
Crucial Note on DoIP Compatibility: For newer Mercedes-Benz models that are purely DoIP-based (starting with model series 206 and 223), specific, Mercedes-Benz tested adapters are required. These adapters are certified for use with XENTRY Pass Thru exclusively for DoIP model series. Mercedes-Benz AG explicitly states no liability for the use of non-approved adapters.
Recommended Pass-Thru Devices for Non-DoIP Models: For Mercedes-Benz models not utilizing DoIP diagnostics, Mercedes-Benz recommends the following pass-thru capable devices that have been tested for compatibility and reliability:
- Actia Passthru+ XS 2G
- Bosch KTS 560
- ADIS Technology EURO VCI
Remember, any Pass Thru device utilized must adhere to the SAE J2534 Pass Thru standard and can be procured from various vendors in the open market.
Important Limitation: XENTRY Pass Thru EU is designed for specific model series and designations as outlined. For workshops requiring full diagnostic coverage across all Mercedes-Benz models and designations, the XENTRY Diagnosis Kit 4 remains the recommended comprehensive solution.
Typically, XENTRY Pass Thru EU contracts are valid for one year and are renewable annually upon payment of the yearly fee, ensuring continuous access to Mercedes-Benz diagnostic capabilities.

Streamlined Registration and Access Procedures
Mercedes-Benz has implemented a two-stage security concept to secure access to and usage of XENTRY Diagnosis software:
Stage 1: Since the 03/2021 release, logging in with a personal user ID and password has been mandatory.
Stage 2: From March 15, 2022, the standard diagnostic role is also required. This role can be requested via the UMAS platform.
Prerequisites: Successful completion of the identification procedure, which can also be initiated via UMAS (unless a local Ident procedure is used in your market). The diagnostic role is then granted via a button on the platform. This identification process via UMAS/IDnow is typically a one-time requirement.
Since Release 06/2020, a robust security framework has been in place to protect diagnostic access and backend services. Personalized logins became necessary for the 213 model update 2020 and 223 passenger car series and extend to all brands and divisions. Anonymous access to vehicles and backend services is no longer permitted.
Since March 15, 2022, the standard diagnostics role is consistently required for all diagnostic activities. For control unit commissioning in series 213 model update 2020 and 223 onwards, the extended XENTRY Flash role is now necessary.
Rights Assignment:
1. XENTRY Standard Diagnosis Rights: Each diagnostic user must independently apply for standard diagnosis rights via https://umas.mercedes-benz.com/umas and complete the one-time identification. Independent Service Providers (independent workshops) without a User ID can apply for one via https://umas.mercedes-benz.com/orgprocess/. Select “New Registration” if you are not yet a registered Mercedes-Benz Group AG customer, or “Registered Organization” if your organization is registered but you lack a personal User ID. Contact your local IT administrator or support via the headset icon on the UMAS page for assistance.
2. XENTRY Flash Authorization: Both Standard-Flash and Extended Flash roles (for all CeBAS vehicles) are requested via UMAS. Each user must undergo a one-time identification via UMAS to obtain Flash roles. Further details on XENTRY diagnostic user rights and Flash rights are available here.
