Important: these functions do not imply full online programming of all controllers or complete replacement of the factory Mercedes-Benz XENTRY system.

AutoVIN – automatic vehicle recognition

The AutoVIN function allows for automatic reading of the VIN and recognizing the compatible vehicle upon connecting the tester. This speeds up the start of diagnostics and reduces the risk of selecting the wrong model.

If AutoVIN does not recognize the vehicle, manual selection can be used. The lack of automatic VIN identification does not automatically mean a lack of compatibility.

CAN FD – support for modern Mercedes vehicles

MB V3.0 supports CAN FD, used by Mercedes-Benz in newer platforms since around 2020.

The manufacturer indicates compatibility with modern platforms such as selected versions of W213, W223, and W167.

The actual availability of CAN FD communication depends on the architecture of the specific vehicle.

All 10 OBDII / EOBD modes

• Read Codes,
• Erase Codes,
• I/M Readiness,
• Live Data,
• Freeze Frame,
• Vehicle Information,
• O2 Monitor Test,
• On-Board Monitor Test,

• Pending Codes.

The tester supports compatible vehicles that comply with OBDII, EOBD, JOBD, KOBD, CAN, and CAN FD standards.

Older Mercedes and Sprinters – optional adapters

MB V3.0 can also work with older vehicles that do not have a standard 16-pin OBDII socket.

MB V3.0 is the generation that introduces full bidirectional control and significantly expanded workshop functions while maintaining a compact design and physical buttons.

Who is iCarsoft MB V3.0 intended for?

• for owners of Mercedes-Benz, Smart, and Maybach,
• for Sprinter users,
• for advanced users servicing their own vehicles,
• for mechanics and diagnosticians,
• for independent workshops specializing in Mercedes-Benz,
• for dealerships and car trading companies,
• for individuals checking a vehicle before purchase,
• for users needing active tests without purchasing a large workshop tablet.

Basic operation step by step

1. Connect the tester to the 16-pin OBDII socket or use the appropriate adapter in an older vehicle.
2. Turn on the ignition.
3. Use AutoVIN or select the vehicle manually.
4. Start scanning available controllers.
5. Read fault codes and Live Data parameters.
6. Before clearing, save DTC and Freeze Frame.
7. If necessary, perform an activation test, adaptation, or service function.
8. After repairs, clear errors and rescan the vehicle.
9. Regularly update the tester via a computer and TF card reader.

Important information regarding compatibility

The range of available diagnostic functions, 39 service functions, active tests, OE adaptations, AutoVIN, and CAN FD depends on the specific model, year, engine, target market, equipment, and ECU configuration.

Not every function is available in every vehicle. Before purchasing for a specific vehicle, we recommend checking compatibility based on the model, year, engine, and VIN number.

In older Mercedes and Sprinters, optional 38-pin or 14-pin adapters may be required.

Advanced adaptations do not imply full online programming of all controllers or complete replacement of the factory XENTRY system.

Clearing a fault code does not remove the physical cause of the fault. If the problem persists, the error may reappear.

Why choose iCarsoft MB V3.0?

iCarsoft MB V3.0 combines full diagnostics for Mercedes-Benz / Sprinter / Smart / Maybach with workshop-class functions. It offers 22+ active tests, 39 service functions, advanced OE adaptations, CAN FD, AutoVIN, and full OBDII/EOBD diagnostics.

A significant advantage is also lifetime free updates, the Polish language, and no mandatory subscription.

This is a very good choice for a user or workshop that needs significantly greater capabilities than MB V2.0 but prefers a compact 4″ tester with physical buttons.
