iCarsoft MB v4.0 Mercedes Benz/Sprinter (+2 other Brands) Scan Tool

The iCarsoft MB V4.0 is a dedicated full-system diagnostic tool for Mercedes-Benz, Maybach, Smart and Sprinter vehicles. It is designed for owners, home mechanics, fleet operators and independent workshops that want deeper manufacturer-specific access than a basic OBD2 code reader can provide.

Mercedes-Benz Group software is installed from the factory, and two further supported vehicle software groups can be downloaded at no extra charge. The V4 platform adds a 5-inch Android touchscreen, AutoVIN, bi-directional testing, 30+ service procedures, CAN-FD support, diagnostic reports and lifetime free Wi-Fi updates.

Why Choose the MB V4.0?

Mercedes-Benz vehicles use a large number of interconnected control modules for drivetrain, chassis, comfort, safety and emissions systems. The MB V4.0 is built to access supported Mercedes-specific modules and maintenance routines beyond the standard engine functions available from a universal OBD2 reader.

Key Features

Full-System Mercedes-Benz Diagnostics

The MB V4.0 is designed to communicate with manufacturer-specific control 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 electronics.

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 vehicle’s model, year, market specification and fitted control modules.

Bi-Directional Control and Active Testing

Bi-directional control allows the MB V4.0 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 windows, mirrors, door locks, throttle actuators, fuel pumps, cooling fans, lighting 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 V4.0 includes commonly used maintenance procedures together with a wider set of Mercedes-specific workshop 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 service, AdBlue functions, crankshaft learning, NOx sensor resets, rain-sensor setup, stop/start functions, radar and camera calibration 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.

Two Additional Vehicle Software Groups

After purchase, two additional supported vehicle groups can be downloaded through Wi-Fi at no extra charge. A software group may cover one make or several related marques, depending on the selection.

The extra downloads add flexibility, but the MB V4.0 remains primarily a Mercedes-Benz specialist. For regular work across many unrelated makes, an all-makes CR Pro or CR Max tool is more suitable.

CAN-FD and Later-Model Vehicles

The MB V4.0 supports CAN-FD communication used by selected newer vehicles. This improves access to compatible later-model platforms that may not communicate fully with older diagnostic hardware.

Some newer vehicles also use manufacturer security gateways that can restrict active tests or service procedures. Exact access depends on the vehicle and manufacturer requirements.

Touchscreen Hardware and Updates

The Android platform uses a quad-core 1.3GHz processor, 32GB internal storage and a 5-inch 854 × 480 capacitive touchscreen. The 5000mAh rechargeable battery provides around six hours of continuous use.

Updates and the two additional software groups are downloaded directly through 2.4GHz Wi-Fi. No annual update subscription is required.

Vehicle Coverage

The MB V4.0 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 diagnostic connector requires careful checking and may require a separate adapter. The adapter is not included with this product.

Is the MB V4.0 the Right iCarsoft Tool for You?

Choose the MB V4.0 if Mercedes-Benz Group vehicles are your main focus and you want a modern touchscreen tool with full-system diagnostics, active testing, strong service capability and two extra software groups included.

Choose the MB V3.0 where physical controls and lower cost matter more. For broad all-makes coverage, move to the CR Pro+ or CR Pro S.
