iCarsoft BMM V4.0 Diagnostic Tool for BMW, MINI & Rolls-Royce

The iCarsoft BMM V4.0 is an advanced professional diagnostic tool designed primarily for BMW, MINI and Rolls-Royce vehicles. It provides full-system diagnostics, bidirectional active tests, advanced maintenance functions and extensive vehicle-specific capabilities in one compact touchscreen device.

BMM V4.0 is the latest generation of iCarsoft’s BMW-focused diagnostic platform. Compared with earlier BMM models, it features a new 5-inch touchscreen, Android operating system, Wi-Fi updates, CAN-FD support and enhanced diagnostic hardware.

The tool comes with BMW, MINI and Rolls-Royce software pre-installed and also allows you to download two additional vehicle make groups free of charge, making it considerably more versatile than a conventional single-brand diagnostic scanner.

Full-System Diagnostics

Unlike a basic OBD2 code reader, the iCarsoft BMM V4.0 can communicate with numerous control units throughout the vehicle.

Depending on the vehicle, diagnostics can include systems such as:

• Engine
• Automatic transmission
• ABS
• Airbag / SRS
• DSC stability control
• Electronic parking brake
• Steering
• Body control systems
• Climate control
• Instrument cluster
• Battery management
• Lighting systems
• Immobiliser and security systems
• Comfort and convenience electronics
• Other manufacturer-specific control modules

The scanner can read and erase diagnostic trouble codes, display live data and help locate faults across multiple vehicle systems.

Bidirectional Control and Active Tests

The BMM V4.0 supports bidirectional diagnostics, allowing the scanner to send commands directly to supported vehicle control modules.

This makes it possible to activate individual components during troubleshooting instead of relying solely on fault codes.

Depending on the vehicle and control module, active tests may be available for components such as:

• Cooling fans
• Fuel pumps
• Valves and solenoids
• Lighting
• Door locks
• Windows
• Relays
• Actuators
• Transmission components

Active testing can make fault finding significantly faster by helping determine whether a component, wiring circuit or control system is functioning correctly.

15 Service and Maintenance Functions

The iCarsoft BMM V4.0 combines everyday maintenance functions with more advanced BMW-specific service capabilities.

Functions include:

• Oil Service Reset – reset oil service indicators and maintenance intervals
• Electronic Throttle Control – throttle body adaptation and relearning
• EPB / Brake Pad Reset – electronic parking brake service
• Steering Angle Sensor Reset (SAS) – steering angle calibration
• DPF Regeneration – diesel particulate filter service functions
• Injector Coding – register or relearn replacement injectors
• ABS Bleeding – activate the ABS system during brake bleeding
• Battery Management Service (BMS) – battery replacement registration and battery management functions
• Body Stability Control Service – DSC-related maintenance and adaptations
• TPMS Reset – tyre pressure monitoring system functions
• Engine Control Service
• Transmission Control Service
• Engine Idle Service
• Mileage Verification
• VIN Verification

Available functions vary according to the vehicle model, production year and installed control modules.

BMW-Specific Diagnostic Capability

The BMM V4.0 has been developed specifically with BMW Group vehicles in mind and provides considerably deeper access than a universal entry-level OBD2 scanner.

It supports major generations of BMW vehicles including E-, F- and G-series platforms, subject to individual vehicle compatibility.

For older BMW models equipped with the round 20-pin diagnostic connector, an optional iCarsoft 20-pin adapter is required.

CAN-FD Support

BMM V4.0 supports the newer CAN-FD communication protocol, helping provide compatibility with newer-generation vehicle electronics as well as traditional CAN-based systems.

This makes the V4.0 a better long-term choice for workshops and enthusiasts working with both older and newer BMW Group vehicles.

Automatic Vehicle Identification

The AutoVIN function can automatically identify supported vehicles through the diagnostic connection, reducing the need to manually select the exact vehicle configuration.

Manual vehicle selection is also available where automatic identification is not supported.

Two Additional Vehicle Make Groups Included

Although the BMM V4.0 is primarily designed for BMW, MINI and Rolls-Royce, the scanner is no longer limited to these vehicles.

In addition to the pre-installed BMW Group software, the user can download two additional supported vehicle make groups free of charge.

This means one device can provide dedicated diagnostic coverage for three vehicle groups without purchasing additional diagnostic software subscriptions.

Lifetime Free Updates

Software updates for the iCarsoft BMM V4.0 are provided free of charge for the lifetime of the device.

Updates are installed directly through the device using Wi-Fi, eliminating the need to connect the scanner to a computer for normal software updates.

There are no annual diagnostic software subscription fees.

Large 5-Inch Touchscreen

The BMM V4.0 uses a 5-inch capacitive touchscreen and Android operating system, providing a more modern and intuitive interface than previous button-operated iCarsoft BMM scanners.

The internal hardware includes:

• Android operating system
• 5″ capacitive LCD touchscreen
• 854 × 480 resolution
• Quad-core 1.3 GHz processor
• 32 GB internal storage
• 5000 mAh rechargeable battery
• Approximately 6 hours of continuous operating time
• Wi-Fi connectivity
• USB 2.0
• USB Type-C charging

Diagnostic Reports

Diagnostic results can be stored in the device’s diagnostic history for later reference.

Reports can also be saved, shared and printed using a compatible Windows computer, making the BMM V4.0 suitable for both private enthusiasts and professional workshops.

Standard OBD2 Functions

In addition to manufacturer-specific diagnostics, the BMM V4.0 supports standard OBD2/EOBD functions including:

• Read fault codes
• Clear fault codes
• Live data
• Freeze-frame data
• I/M readiness
• Vehicle information
• Oxygen sensor monitoring
• On-board monitoring
• EVAP system testing
• Pending fault codes

Supported Languages

The BMM V4.0 supports multiple interface languages, including:

English, German, French, Dutch, Spanish, Czech, Swedish, Russian, Hungarian, Norwegian, Portuguese, Italian, Polish, Danish and Finnish.

Compatibility

The iCarsoft BMM V4.0 is primarily intended for BMW, MINI and Rolls-Royce vehicles.

Standard 16-pin OBD connectivity is used on compatible vehicles from approximately 2001 onwards. Earlier BMW models using the round 20-pin diagnostic connector require a separate iCarsoft BMW 20-pin adapter.

Diagnostic coverage and individual service, coding and active-test functions always depend on the exact model, production year, engine, control unit and vehicle configuration. Compatibility should therefore be confirmed for the specific vehicle when a particular advanced function is required.

Why Choose the iCarsoft BMM V4.0?

The BMM V4.0 is an excellent choice for BMW Group owners, enthusiasts and workshops that need more than simple fault-code reading.

With full-system diagnostics, bidirectional active tests, CAN-FD support, advanced BMW service functions, a modern touchscreen interface and lifetime free updates, it provides a powerful diagnostic package without recurring software subscription fees.
