Genuine users’ experience:

  1. I have checked if you can write me Kess v2 5.017 and software version 2.47 your control unit. It’s normal for me to be able to read and write. It uses Protocol 164.


  1. you can read write it with your clone
    keep voltage above 13v during writing.



I can confirm that most kess clones have problem with such ecu. I personally had problem with such ecu on mini cooper (bmw) during writting. I had to restore by bench.
After that, i do such ecus on bench by ktag.


It’s not a tool problem, bmw needs good and steady battery voltage while writing.


Where to have good working Kess V2 5.017 RED PCB?

Since there are dozens of supplier/sellers, and not sure all are 100% same.

But this one is reliable, bought 10pcs and all are tested. As I known, the QC label on the tool means they checked every tool before shipping out.




  1. I can confirm that Kess v2 5.017 is reading works perfectly on K-Line but I am afraid to Write the ECU.

    I did a full Read it took me 34 Minutes to full read over OBD.


Therefore, I want to say, it´s not necessary to use genuine tools like a professional do, when it is not the tool’s problem. Kess v2 5.017 software 2.47 is enough.
