Where is the water pressure expansion tank sensor located
If the gauge is showing nothing (not even zero) then more than likely it’s the sensor. I had that happen twice. Before replacing sensor check the connection at the sensor as it could have a loose wire inside the square cap.
If you happened to open the cap when the engine is warm it will lose that pressure. Then u need to pump up with air. If u let it sit overnight and start it up then it will build pressure as normal.
Do you have a picture of the sensor
I have a coolant pressure water pump aft fault any thoughts
Skip sold his Xabo so not sure if he is still following the forums.
Most likely the sensor.
