An engineering application, not XENTRY
Vediamo is a Mercedes-Benz engineering diagnostic application. It is not XENTRY Diagnosis and it is not DAS. Dealer guided tests, workshop information and online commissioning remain the factory workshop path described on the factory diagnostic equipment page. A workshop copy of Vediamo does not establish that an SCN or control-unit commissioning procedure can be completed offline.
The version 05.00 handbook, dated September 2012 and identified as Mercedes-Benz PWT/VEP, expands the name as Verteilte Diagnose Anwendung für Motoren, a distributed diagnostic application for engines. The same introduction says the program is no longer limited to engine control units. That handbook is an internal document. The wording here is taken from its introduction as reproduced outside Mercedes-Benz, including copies that preserve the German expansion and the PWT/VEP title-page identification. It is not a current public product page, and later unofficial builds are not treated as part of that 2012 text.
CAESAR, DIOGENES and the files they use
The handbook places Vediamo in the CAESAR/DIOGENES process chain. CAESAR is the communication platform: the diagnostic server talks to the selected interface through CAESAR drivers. DIOGENES is the diagnostic-data source. The handbook names three file roles that matter when identifying a dataset:
- CBF, the DIOGENES diagnostic description for a control unit.
- CCF, a coding file.
- CFF, the CAESAR flash container. The handbook says programming from this application uses CFF rather than a raw BIN, HEX or S19 file directly.
Those names identify data formats in the engineering chain. They are not a procedure for building a flash file or for writing one to a vehicle.
The 2012 introduction says diagnosis is available over K-line and CAN, and lists the protocols RTMD+, MBISO, KWFB, KW2000 and UDS. It gives Part A, Part C and Part Y as examples of CAESAR communication hardware, and the hardware section also names Part W as SDconnect and Part P as an eCom/MVCI device. Which of those interfaces a particular installation actually supports has to be read from that installation. The same introduction says later versions were intended to move onto MVCI and to support ODX. That is a 2012 statement about intended later versions, not a description of every copy in circulation.
What the handbook says the software contains
Vediamo is a client-server application. The handbook’s module list includes a diagnostic server (DiagServer), a start centre, a system-configuration tool, and Ecoute as the interactive diagnostic client. It also describes Java programs, logging and simulation when no interface is connected. The functions named for Ecoute include control-unit selection, diagnostic services, fault memory, a quick test, variant coding, flash programming and OBD. Those are engineering operations against the loaded diagnostic data. Menus and available services change with the CBF and the control unit; the handbook does not make every service available on every Mercedes road car.
This page does not include a Vediamo screenshot. A verified image from Mercedes-Benz or from the handbook file itself was not used, and reseller demonstrations are not a substitute.
How this differs from DTS Monaco and from dealer diagnosis
DTS Monaco is a Softing product aimed at ODX diagnostic databases. Vediamo, in the 2012 handbook, is the Mercedes CAESAR/DIOGENES application. Public Mercedes development advertisements show DTS Monaco in current engineering work. They do not say that Monaco replaced Vediamo, and this page does not invent that handover.
XENTRY and DAS present guided workshop tests and, where the account and the vehicle allow it, control-unit commissioning. Vediamo presents the diagnostic services described in the engineering data. Sellers who advertise Vediamo as an unrestricted offline substitute for online coding are going beyond what the handbook introduction establishes. Variant coding, SCN and flashing are distinguished on the SCN coding page.
