Why Choose the iCarsoft BMM V4.0?

BMW Group Software Plus 2 Extra Vehicle Groups

The BMM V4.0 is ready to use with BMW, MINI and Rolls-Royce software installed. You may then choose and download any two additional vehicle make groups from the list below.

OE-Level Full-System Diagnostics

Access supported vehicle control modules through the diagnostic socket to read and clear DTCs, view ECU information, display live data and examine Freeze Frame records.

15 Comprehensive Service Functions

The BMM V4.0 combines nine commonly used maintenance functions with six higher-level professional routines. Availability varies by vehicle, system and software level.

Advanced BMW ECU Coding

The BMM V4.0 supports selected ECU coding, adaptation and data-restoration functions on compatible BMW vehicles, including coverage across major E-, F- and G-chassis generations.

E- to G-Chassis Support: access compatible control units on many BMW models manufactured from approximately 2006 onwards.

DME/DDE repair and data restoration: selected functions may help recover corrupted data or address supported software-related issues in engine control modules. Coding availability varies substantially by model and ECU, so request a coverage check where a specific coding task is essential.

Advanced Bi-Directional Active Tests

Bi-directional control allows the BMM V4.0 to send commands directly to supported vehicle modules. This helps separate wiring, switch, module and actuator faults without unnecessary dismantling or parts replacement.

Examples may include the A/C blower fan, windows, mirrors, locks, fuel pump, throttle actuator, ABS pump, lamps and other components. Available tests vary considerably by vehicle.

Lifetime Free Wi-Fi Software Updates

The BMM V4.0 includes lifetime free online software updates with no annual subscription charge.
