iCarsoft BMM V4.0 - BMW, MINI & Rolls-Royce Diagnostic Tool
Advanced V4 platform with Android, internal battery and Wi-Fi updates - purpose-built for BMW Group vehicles.
The iCarsoft BMM V4.0 comes with BMW, MINI and Rolls-Royce software pre-installed and is ready to use out of the box. It also allows you to add 2 extra vehicle brand packages free of charge, making it a strong option for mixed-vehicle households or workshops.
BMM V4.0 is designed for home mechanics, DIY users and professionals who want full-system diagnostics, service functions, active tests and modern Wi-Fi updating in one easy-to-use handheld scanner.
Who is BMM V4.0 best for?
BMW Group owners
- BMW, MINI and Rolls-Royce software pre-installed
- All-system diagnostics beyond basic engine code reading
- Useful maintenance functions for supported vehicles
Ideal if you want a dedicated BMW Group scanner without stepping up to a much larger workshop tablet.
DIY and home mechanics
- AutoVIN for quicker vehicle recognition
- Live data in text and graph form
- Bi-directional tests on supported systems
Great if you want more than a basic OBD2 code reader and like doing your own fault finding.
Garages and mixed-brand users
- Add 2 extra brands free of charge
- Wi-Fi updates directly on the tool
- Portable use with built-in battery
A practical choice where BMW Group is the main focus but you still want coverage for a couple of other makes.
Before you buy - quick compatibility check
Coverage can vary by model year, ECU and system. If you want us to confirm exact functions for your BMW, MINI or Rolls-Royce, send your registration number or VIN and tell us what functions you need.
Important: older BMW models using a 20-pin diagnostic socket need a separate 20-pin to 16-pin adapter lead. This adapter is not included with the scanner.
This helps avoid ordering the correct tool but expecting a function that may not be supported on your exact vehicle.
