Choose V2.0 if you need full-system diagnostics plus 9 common service functions such as EPB, DPF, BMS and injector coding.
Choose V3.0 when bidirectional active tests and more advanced troubleshooting are important, but you do not need the newer touchscreen platform.
Choose V4.0 for the most advanced current BMM-series standalone experience with active tests, BMW ECU coding, 15 service functions, Wi-Fi updates and two additional vehicle groups.
The iCarsoft BMM range is the most direct choice for a dedicated BMW scanner, but other platforms make more sense in specific situations.
Best when: you own or work with several German vehicle brands.
DE V4.0 combines BMW, Mercedes-Benz and Volkswagen Group diagnostics in one standalone scanner, with 48 service functions and BMW/VAG ECU coding on supported vehicles.

Launch X431 platforms provide broad multi-brand workshop diagnostics with full-system access, active tests, coding and service functions on supported BMW vehicles.
A manufacturer-specific BMW scanner can access far more than the generic engine functions available through a basic OBD2 code reader.
Read and clear faults, view live data and access supported engine and automatic transmission control modules.
Diagnose ABS, DSC and related braking or stability systems where supported by the vehicle.
Access supported restraint-system control modules and diagnose airbag-related fault codes.
Access supported body modules, climate control, lighting, parking systems, seat electronics and other BMW-specific systems.
Depending on the scanner and vehicle, functions can include oil reset, EPB service, battery registration, DPF regeneration, ABS bleeding and steering-angle calibration.
BMM V3.0, BMM V4.0 and professional platforms can command supported components during diagnosis. BMM V4.0 also supports selected BMW-specific ECU coding and adaptation functions.
Compatibility depends on both the BMW generation and the diagnostic function you need.
The iCarsoft BMM range is designed specifically for BMW Group diagnostics and supports major BMW generations including E-, F- and G-series vehicles, subject to exact vehicle and function compatibility.
BMM-series scanners also support compatible MINI vehicles, with available diagnostic and service functions depending on the model generation and installed control modules.
BMM-series coverage includes supported Rolls-Royce vehicles that share BMW Group diagnostic architecture.
Selected older BMW models use the round 20-pin diagnostic connector. These vehicles require a separate iCarsoft BMW 20-pin adapter.
BMM V1.0 is suitable for basic full-system diagnostics, while BMM V2.0 adds more maintenance functions. BMM V3.0 adds bidirectional active tests, and BMM V4.0 combines advanced diagnostics with BMW ECU coding, a 5-inch Android touchscreen, Wi-Fi updates and two additional vehicle groups.
Both support full-system diagnostics and bidirectional active testing. BMM V4.0 adds a 5-inch Android touchscreen, Wi-Fi software updates, two additional vehicle groups and broader BMW-specific coding functionality.
