Unfortunately, I do not remember this service action, but once I fought with the sensor and if the module was programmed, e.g.
On a car with this small 28-liter tank, the sonar did not show anything or the value was constant, e.g. half a tank.
It is known that it is more work, but change to your original driver from the pump, you will exclude the sonar.
How did you change the sonar, not even an adblue droplet flew to the plug? Because it will be sonar.
Do you have a second 5 euro mana?
Several times, to quickly rule out various errors with which they fought before me, I put 2 mana in parallel and connected the plug, for example, the orange one to the other one, and I excluded, say, sonar.
