What does XENTRY Diagnosis Lite have to offer?

Exclusively for independent workshops, we offer a special diagnostic solution for standard PCs: 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.

Who may order XENTRY Diagnosis Lite?

Exclusively for independent operators based on the EC regulations (715/2007, 692/2008, 595/2009, 582/2011, 64/2012 and 2018/858). In order to process your request as quickly as possible, we require an evidence confirmation that you belong to the authorized group of persons (motor vehicle workshop or other company dealing with motor vehicle repairs). This requires the upload of relevant documents (e.g. trade licence, entry in the commercial register, verification of professional qualification in the motor vehicle trade, or another official document proving the purpose of the business).

What do I have to consider when ordering XENTRY Diagnosis Lite?


  • XENTRY Diagnosis Lite can only be ordered for a standard PC that does not have an active StartKey/contract.

  • Customers with an active StartKey/contract for a XENTRY Pass Thru EU system cannot order XENTRY Diagnosis Lite for the same hardware ID. They must always use another unoccupied standard PC for this purpose or wait for the contract end of the XENTRY Pass Thru EU system.

IMPORTANT - New compulsory Login procedure

Our new security concept secures access to and use of the XENTRY Diagnosis software in two stages:

You log in with your personal user ID and password, and you also need the standard diagnostics role.
You apply for this via the UMAS platform.

Prerequisite: You have successfully completed the identification procedure. You can also start this via UMAS, unless a local identification procedure is used in your market. You will receive your role via the corresponding button on the platform. Basically you only have to go through the identification process via UMAS/IDnow once.

This security level applies to all brands and divisions, i.e. all diagnostic users must log in personally to the diagnostic device. This means that anonymous access to vehicles and back-end services is no longer possible.
In principle, you will always need the standard diagnostics role for all diagnostic activities. To control unit commissioning from series 213 model update 2020 as well as 223, the new extended XENTRY Flash role is required.

The respective rights are assigned as follows:

1. XENTRY standard diagnostic rights:

Each diagnostic user must independently apply for the standard diagnostic right via https://umas.mercedes-benz.com/umas/ and carry out the one-time identification. If you are an independent service provider (independent workshop) and do not yet have a user ID, you can apply for a respective one via the following link: https://umas.mercedes-benz.com/orgprocess/.

Please select "New Registration" if you are not yet registered as a Mercedes-Benz Group AG customer. Or select "Registered Organization" if your organization is a registered customer but you do not have a User ID.

Please contact your local IT administrator. Alternatively, you can contact support via the support button on the very right side of UMAS page (headset icon).

2. XENTRY Flash authorization:

Both XENTRY Flash-roles (Standard-Flash role and Extended Flash role for alle CeBAS vehicles) can be applied via UMAS.
Each user must independently carry out a one-time identification via UMAS to get the Flash roles.

More information on XENTRY diagnostic user rights and Flash rights can be found here.
