Voluntarily and based on the EC Directives (715/2007, 692/2008, 595/2009, 582/2011, 64/2012 and 2018/858), we offer independent market participants a special diagnostics solution for standard PCs: XENTRY Diagnosis Lite.

The operation of this XENTRY Diagnosis variant does require a XENTRY Diagnosis VCI.

Exclusively for independent workshops, we offer a special diagnostic solution for standard PC: XENTRY Diagnosis Lite. You can operate this voluntarily offered product variant on a standard PC. The scope of delivery includes the standard XENTRY Diagnosis VCI hardware to communication with the vehicle. It offers a full diagnostic scope:

• Quick test

• Basic diagnosis (actual value, actuations)

• Commissioning (incl. flashing, coding and parameterization)

• Fault memory reading / deleting

• Guided diagnosis

• Functional diagnosis

• Repair forecast

• Key programming, FBS4 services available from August 2023!

• Diagnosis for all control units for all model series from 2004 (XENTRY and DAS series / no HHTWIN)

The initial order of XENTRY Diagnosis Lite includes a download link with user documentation for Basic Setup installation on Windows PCs with service updates throughout the contract term. A contract number, a StartKey and time credits are required for the use of the software.

For the first contract year, no flat user fee is billed for software usage and support. After the first year, the subscription to XENTRY Diagnosis Lite can be renewed one year at a time by paying another annual flat user fee. This entitles you to receive continued regular updates of applications and data and to use the online services as well as user support.

For a new order of XENTRY Diagnosis Lite, the following components are included in the XENTRY Diagnosis COM Kit:

1. XENTRY Diagnosis VCI
2. WiFi stick
3. OBD cable (16-pin)
4. USB cable (5m)
5. User information and safety instructions
6. Digital components (software, manual, help cards)

Important note:
Please note that XENTRY Diagnosis Lite can only be ordered by users with a registered office in the European Union, Iceland, Liechtenstein, Norway, Switzerland, the United Kingdom of Great Britain and Northern Ireland.

A special hardware-dependent StartKey is required for the use of XENTRY Diagnosis Lite, which can only be ordered in the Mercedes-Benz B2B Connect after receiving the initial delivery. The hardware ID required for ordering the StartKey can be read via the tool "ConfigAssist"; the system or contract number also required for XENTRY Diagnosis Lite can be obtained from Mercedes-Benz B2B Connect "My workshop" > "Applications" > "XENTRY Diagnosis Lite" > “Overview of system & credit".

The StartKey enables certain end devices such as laptop computers to run the diagnostics application when you use the unique hardware ID for ordering. The end device must meet the following system requirements:

• Administrator rights for installation and updates

• Windows-compatible PC/laptop with at least Intel I5 processor or comparable model

• Operating system: Windows 10 (64 bit) or Windows 11 (64 bit)

• At least 8 GB main memory (RAM), 16 GB recommended

• Minimum 150 GB available hard drive space, SSD hard drive is recommended (due to performance and mechanical durability)

• Browser: Edge for Windows

• Broadband Internet connection via LAN/WLAN

• Microsoft .NET 4.0 (or higher) installed (http://www.microsoft.com)

A permanent online connection is required to use the diagnostic content:

• for the retrieval of diagnostic data (for each diagnostics session)

• to check access right to data content (StartKey)

• to check contractual data

Yes. XENTRY Diagnosis Lite is an online diagnostics solution. When starting XENTRY Diagnosis Lite application, access rights and application data are reconciled. This check fails without an online connection and XENTRY cannot be started. In addition, when opening the diagnostics from the XENTRY frame, the available time credits of the user account are retrieved online. If the credit cannot be verified online, the diagnostics cannot be opened.

No. The hardware in form of the XENTRY Diagnosis COM Kit can be only purchased and is not available for rent. 

Due to a new PC/laptop/tablet, the current start key of a XENTRY Pass Thru EU/XENTRY Diagnosis Lite no longer works.
The hardware ID associated with the startup key needs to be changed. 

To do this, follow these steps:

• Log in to B2B Connect and navigate to "Account" > "Licenses"

• Under "Active Licenses", select the system in question, e.g. XENTRY Pass Thru EU.

• Click "Change" next to the hardware ID

• Then enter the new hardware ID and confirm with "Save".

Once the change is complete, the system is associated to the new hardware ID. You will receive an automated email confirming the change.

The use of XENTRY Diagnosis Lite requires payment of a yearly flat user fee and the purchase of a XENTRY Diagnosis COM Kit via Mercedes-Benz AG; time-related, additional costs are incurred for access to diagnostic data.

• Billing for the use of diagnostic data and application

• Time-based billing of a flat user fee for online operating costs and support

• Time credits for diagnostics data can be purchased in different amounts

• For billing modalities and the prices for the flat user fee and time credits, please visit the XENTRY Diagnosis Lite product page

• The initial order, follow-up order and ordering time credit processes are described under "Registering and ordering"

The use of XENTRY Flash within XENTRY Diagnosis Lite is password protected. A XENTRY Flash user authorization is required for every individual diagnostics user in order to gain access. Please apply for this rights via UMAS.

XENTRY Diagnosis Lite is initially provided for 12 months with the purchase of the XENTRY Diagnosis COM Kit. The contract ends automatically after this time. Renewals can be purchased one year at a time with the payment of additional annual flat user fees.

Only the actual usage time of the diagnostic content is billed via the diagnostic time credits; the costs incurred for users are therefore usage-based and not flat-rate. The usage fees, which cover all fixed costs such as administration, sales and permanent availability of support, can be kept lower through the separate time credits for the actual diagnostic content.

Your remaining current time credit – for the selected vehicle division – is displayed each time you open the diagnostics (start of diagnostics in the XENTRY frame).

Your time credit status is also indicated in the Mercedes-Benz B2B Connect under “My Workshop” > “Applications” > “XENTRY Diagnosis Lite” > “Overview of your systems & credits”.

The status of the diagnostics time credits is checked every time the diagnostics are started from the XENTRY frame for a specific vehicle. If no "partially used" time credit exists, the next available time credit is used. The time credit starts running continuously from that moment, even if the diagnostics or XENTRY are shut down. As an example, if the diagnosis only takes a few minutes and XENTRY is then closed, a one hour credit will only last for the hour following activation. If you try to start the diagnostics after the hour has passed it will activate a new time credit. If your time credit runs out during a diagnostics session, the diagnostics can still be continued until the next vehicle change.

The subscription to XENTRY Diagnosis Lite comprises both a fixed and a variable price component.

Fixed price component

• Product-specific annual flat user fee for online operating costs and the use of support services

Variable price component

• Consumption of the purchased time credit units for the use of diagnostics data

• Automatic management of the use time credits (by the diagnostics application)

• A credit unit is activated when the diagnostics system is opened and continues to run until it expires even after having ended the diagnostics session or after having changed vehicles

Please Note:
Unfortunately, any time credits purchased by mistake or that are no longer required cannot be returned or refunded. Unused or not started time credits also cannot be refunded at the end of the contract period. However, your credit will be transferred if you renew the contract.

Ordering flat user fee and as time credits:

• Ordering of time credits for XENTRY Diagnosis Lite can only be ordered in Mercedes-Benz B2B Connect

• Other order methods (such as fax, email, ordering from Mercedes-Benz AG by phone, ordering via national organization/MPC or via Mercedes-Benz agent etc.) are not possible
