Hi there - ive got a Sabvoton 80A controller and QS 3KW motor on my enduro build. Been used with no problems over the past year and recently started getting an "error 30h communications error" on the UKc1 display. When it displays i can still change it from "P" (Park) to mode 1 and drive it, but im unable to change to mode 2 or 3 or see the speed, since the error is still displayed on the screen.
Its basically the same error you would get when you removed the 3 pin cable to program the controller over bluetooth...its just there all the time. I tried to connect to it over the MQCon app and I can see the controller and initially connect to it with the green "normal" button, but then a second or two later it shows 0 values and "restart" on the app, like its not connected.
Some of the 3 pin cable wires were slightly frayed so i assumed that must be the issue. I cut those out and put in new ones, but no change. I also unplugged all cables except the ignition and display cable, and still no change. I took apart the controller and saw no visible issues.
So a bit stumped. NB Power is usually pretty good with their support but wasnt so helpful and wants to charge me to buy a new controller.
