  • *****twin b diagnostic tool

    By Issy khan

    a fantastic opportunity to use both the BMW and Mercedes software on one laptop.

    this is a must have tool for any professional or garage that is consistenly working with the above vehicles.

    i have many professional tools but they are unable to diagnose Mercedes accurately like this tool. Also BMW and Mercedes software, both provide part numbers, diagnostic maps and photographs of components and wiring diagrams.

    a must have tool!! recommended to all- the launch cannot do what this tool can!!

    Call UK Diagnostics: 07904 371 888 in Greater London area for all diagnostics including Remapping - DPF Removal - Airbag Crash Data & more
