[Solved] Stag Gofast Gas Level Indicator Failure - LED Panel & Multivalve Voltage Issues

Hello!
The problem appeared after several days of efficient use of the installation.
One day, the LED panel simply stopped indicating the level in the button without lighting any diodes except the one that indicates the fuel on which the car is running. The image of this button is similar in the program, with the difference that it shows only the red one.
And the hit itself is that in the settings tab, the voltage from the indicator on the multivalve is seamlessly displayed and shows 3.64V, fluctuating slightly while driving. According to the thresholds I have set, three of the four LEDs should illuminate, but this is not happening - photos below. The sensor on the multivalve is set to standard, but even if I change it - it doesn't help. However, I know from experience that even if I set the wrong one, at least one red reserve LED MUST be on, and nothing ...
Maybe some of you had such or a similar case? Maybe it's just a released driver, but I'd rather be sure before sending it in for a complaint.
I would like to add that the LED panel passes the test without any problems from the program. In a sense, it enlightens all in turn as they should.

The switch works?
It is best to drive to someone who has such a switch because the problem may be, for example, in the controller.
I have never had such a fault before and I have installed a lot of them.
You can still check the switch updates or try to upload with your finger.

I have a second switch, but this one looks good ... I took it out, checked the cables. They are intact, in term shirts, wrapped in tape - I put it on myself I do not have this vehicle at home now, but if I replace it, and until then I do not miss anything, I will probably put a second switch. However, the test from the program passes the ideology - it lights the diode behind the diode ... The LPG / gasoline switching itself also works.
The type of sensor set was the one suggested from the set - as in the photo, but whatever I choose there, no diode fires, even the red reserve. On the icon in the program, only the red one lights up and when the sensor type is changed, it will not vibrate either. That's why I suppose the problem isn't with the switch itself, but maybe the driver, or some option that I haven't noticed so far ...
However, you intrigued me with this switch update - can it be uploaded at all ?? How to do it

Save the controller settings, restore the factory settings, upload the older software and then the new one again to the controller. The switch is already digital, not analog, as you can see 3 wires, not like in the old 5. So the driver sends info and the switch processes it for display.

Yes, I will. I haven't uploaded the older software so far (where to get it ...), but if it's going to help, it's worth trying. I understood that you suggest to upload soft to the button we did not understand each other. I realized that the switch has a digital connection, but ... not so much that it can upload soft

The technique has moved on.

I mean, download the older version of the Stag 200 Easy program and there will be the older driver firmware in it - and upload it anyway? Is there a firmware file somewhere, because I can't dig into something like that ...

It should be in an older version of the program.

Because if we do not withdraw the software, it sees a new one and does not want to update it.

The solution turned out to be prosaic - the problem lay in ... powering the LPG control unit
Replacing the fuse with a new one completely fixed the problem

Hi, I have the same problem as my friend.
The clock on the cylinder shows the status but not on the display.
Will you tell me where this fuse is?
The car has just been bought and I have never dealt with gas in my life.

For those who are struggling with this problem. Just remove and insert the fuse next to the battery. It helped me.
