I worked with Ruan also and another tech. They were courteous and responsive. We got nowhere.
A real problem with dealing with them is the time difference. The most we could do was one email exchange a day, sometimes taking two days, and there was no exchange over weekends.
My problem, simply put, is I cannot install the app on the windows 10 laptop.
I can get it to work via wifi, but as you know that has VERY limited functionality.
Via wifi, I can read fault codes, but because I cannot install the app on the laptop, I really can't do anything else. That's it, just read the fault codes.
I kept playing with it on my macbook pro and for a moment I was able to reset my service reminder, just don't ask my how I accomplished that or ask me to do it again, I may try it again.
