XENTRY Diagnosis has become even more secure!

For commissioning, programming and coding of ECUs (XENTRY Flash) an additional, second authentication is mandatory for each user. This process is similar to a TAN authentication as requiered for online banking.

For authentication, you need one of the following two factors:

  • Smartphone authenticator app (e.g. PingID, Microsoft Authenticator)

OR

  • USB security key
    You can use any key of your choice, as long as it supports the FIDO2 standard.
    Available from specialist electronics retailers or directly from the manufacturer.

We recommend that you set up both options right away. If you lose one of the authentication factors, you will be able to work with the second one!

To assist you in setting up the factors, we will provide you with a compact HelpCard for download.

Reset of the second factor

If you are no longer able to authenticate, you have several options:

1) If you have lost/forgotten your smartphone, but you have set up another second factor (USB security key), you can use that one.

2) If you don't have an alternative second factor set up, contact your org admin. The org admin can reset the second factor for you so that you can create a new one. If you don't know your Org admin, you can check it via Alice under your profile data. To do this, click on "Administrators".

Multiple uses for your workshop

Whether for flashing, SCN/CVN coding or entering equipment codes: XENTRY Flash can be used with Mercedes-Benz Cars (including smart*, Maybach and SLR) as well as with Mercedes-Benz Vans. For trucks, we offer an online process for the parameterisation of control units, which speeds up data availability in the workshop after a control unit replacement.
Conveniently, all processes are fully integrated within the diagnostics software (XENTRY Diagnosis, XENTRY DAS) requiring fewer manual intervention from your mechanics.

* except smart model #1

Automatic SCN coding and VeDoc reverse documentation

After the programming of the control unit, the SCN coding (if permitted by the control unit) as well as the reverse documentation will run automatically in the VeDoc Vehicle Documentation System. Any changes made to the vehicle or the control unit software are updated on the VeDoc vehicle data card.

Single sign-on for convenient working (Single-Sign-On)

Once you are logged into one of our workshop applications (e.g. XENTRY Flash, WIS etc.), no further sign-on to the central online systems is required, resulting in smooth workflow in your workshop. The user is logged out of the online systems only after one hour of inactivity.

Diagnosis User Rights

New diagnosis user rights as of 06/2020

With the introduction of the E-Class facelift and the new S-Class, a new security concept is being introduced, which will also have a significant impact on the use of XENTRY Diagnosis software.

As of the 06/2020 data release, a prompt to enter a personalised user name and password will appear when accessing the new E-Class and S-Class. It is not possible to diagnose these vehicles without entering this information. This means that these vehicles can no longer be repaired/diagnosed without diagnosis access authorisation. Every user must go through an identification process in order to acquire the corresponding user rights for the facelift of the E-Class and subsequent models. Please note that it is no longer possible to diagnose these model series with a XENTRY Diagnosis Kit 2. You will need a XENTRY Diagnosis Kit 3 as a minimum.

A distinction is made between two types of user rights:

  • XENTRY Standard Diagnosis (for diagnosis users without XENTRY Flash authorisation, e.g. for reading and erasing fault memories)

  • XENTRY Flash user (corresponds to the current XENTRY Flash user)

Please use one of the following options:

XENTRY Flash rights:

  • User already has Flash rights: Every Flash user must independently go through the one-off identification process at https://umas.mercedes-benz.com/umas.

  • User does not have Flash rights: User must request XENTRY Flash rights through the market-specific channel. They must then go through the identification process at https://umas.mercedes-benz.com/umas

XENTRY Standard Diagnosis rights:
Every diagnosis user must independently request the Standard Diagnosis rights via https://umas.mercedes-benz.com/umas and run through the one-off identification process. It may also be necessary for the market-specific ISP support to create the user in GEMS if they do not yet have a user ID.

What is certificate-based diagnosis and why was it introduced?

The vehicles are developing ever gradually into a "mobile computer". This in turn makes the vehicles the target object for hacker attacks and misuse. The number of news items in the press has grown massively. UNECE regulations will, in future, require protection of the vehicles. Mercedes-Benz is also introducing corresponding security measures.
To help protect against any unauthorized diagnosis access, the new Mercedes-Benz vehicle software architecture is now available with user-related security certificates.

Which vehicles are affected?

Certificate-based diagnosis was introduced in E-Class facelift vehicles (model series W213 facelift) with individual control units. The S-Class W223 saw the full introduction.
In future, all new model series and facelifts will be equipped with certificate-based diagnosis.

What changes have been made to the diagnosis?

In future, to enable diagnosis to be performed, you will require a certificate provided by the manufacturer. At the start of a diagnosis session, this certificate is exchanged between the tester and the vehicle. This process is filed in the tester application and it runs in the background.

Where can a certificate be obtained? What is the registration process like?

You are an independent workshop:

  • If you own a XENTRY Diagnosis Kit 3 or 4, or if you use XENTRY Pass Thru EU, the certificates are provided by Mercedes-Benz AG.

  • If you own a diagnosis tool from an independent manufacturer, the certificates are provided by the tool manufacturer, if it has concluded a data license agreement with Mercedes-Benz AG.

You are a diagnosis tool manufacturer:

You are a technical inspection agency or an official bureau:

Which costs will be incurred by a customer?

The certificates are made available by Mercedes-Benz AG to all customers free of charge.

Which data are required? (Personal reference/identification etc)

This is dependent on the level of access involved.

  • Read access authorizations are bound to an organization and they must be issued for an organization/service operation

  • Write access authorizations are personalized and require previous personal authentication - either at Mercedes-Benz AG or at the independent tool manufacturer.

What can still be read out and is still available without restriction through OBD? Which functions can I no longer perform without a certificate?

OBD-II functions (SAE J1979) are still available without any restrictions.
For all further functions, diagnosis certificates are required that are either bound to an organization or to a person, depending on the level of access authorization involved.
