  1. Hi,

    Will this work with mercedes A-class -12/13 to release the handbreak wich is electronic?
    Or do I need to update it? I got software 2.0. Tried this morning with no success 🙁

  2. Hi Tim,
    I just bought my KW850 from China and all the time I use in Japanese cars 1997 onward models it gives me an error message “Error in communication with vehicle ECU”. I made sure the tool is connected to the vehicle’s DLC, the ignition is ON and the vehicle is OBD2 compatible. I even updated the tool online.
    You have any idea of what can be done to make it work?

    Thanks,
