iCarsoft MB v3.0 Mercedes Benz/Sprinter Scan Tool

The iCarsoft MB V3.0 is a dedicated Mercedes-Benz Group diagnostic tool for owners, home mechanics, fleet users and smaller workshops that want deeper access than a basic OBD2 reader without moving to the newer touchscreen platform.

It provides full-system diagnostics on supported Mercedes-Benz, Maybach, Smart and Sprinter vehicles, together with bi-directional active testing, AutoVIN, live data, diagnostic reports and more than 30 service, reset and relearn functions.

Why Choose the MB V3.0?

The MB V3.0 is a strong choice where Mercedes-Benz Group vehicles are the main focus and a simple, durable handheld is preferred. It is vehicle-powered, ready to use when connected and does not rely on an internal battery during diagnosis.

Key Features

Full-System Mercedes-Benz Diagnostics

The MB V3.0 is designed to communicate with manufacturer-specific modules throughout supported vehicles. Depending on the model, this can include engine, transmission, ABS, airbags, steering, instrument cluster, body control, climate control, electronic parking brake, air suspension, lighting, seats, security, gateway modules and other fitted systems.

Available functions include reading and clearing fault codes, viewing ECU information, checking live data and freeze-frame information, carrying out a complete vehicle scan and opening individual modules for more focused diagnosis.

The exact systems available depend on the model, year, market specification and fitted control modules.

Bi-Directional Control and Active Testing

Bi-directional control allows the MB V3.0 to send commands to supported modules and components rather than only reading stored information. This can help confirm whether a component responds before replacement parts are ordered.

Depending on the vehicle, active tests can include EVAP components, ABS pump motors, windows, sunroofs, door locks, mirrors, throttle actuators and other supported electrical systems.

Active-test coverage varies by model, year and fitted ECU. A test available on one Mercedes-Benz vehicle may not be available on another.

30+ Service, Reset and Relearn Functions

The MB V3.0 includes commonly used maintenance procedures together with a wider range of Mercedes-specific routines.

Additional supported procedures can include transmission adaptations, air-conditioning service, headlamp calibration, engine and body-control adaptations, seat and window calibration, fuel-pump activation, immobiliser-related functions, AdBlue routines, crankshaft learning, NOx sensor resets, rain-sensor setup and other vehicle-specific operations.

Service-function availability varies by model, year, system and ECU configuration. A listed function is not available on every supported vehicle.

Updates and Diagnostic Reports

Software updates are installed through a Windows computer using the supplied USB cable and storage card. Updates remain free for the life of the tool, with no annual subscription.

Previous diagnostic sessions can be accessed from the tool, and reports can be saved or printed through a Windows computer for workshop records or customer documentation.

Vehicle Coverage

The MB V3.0 supports many OBDII-era Mercedes-Benz passenger vehicles, AMG models, Maybach, Smart and Sprinter applications using the standard 16-pin diagnostic connection.

Coverage on early Mercedes-Benz vehicles using the older 38-pin connector requires careful checking and may require a separate adapter. The adapter is not included with this product.
