Windscreen Washer Bottle Level Indicating empty when it's full.

[Hendersd]

Hi, I have an annoying issue where I get an indication that my windscreen washer bottle is empty when it is in fact full. Conversely when the bottle is nearly empty the indication disappears. I have had the sensor replaced to no avail. I am thinking that car's computer may need to be reset. Has anyone had this problem or have any suggestions on how to fix it, before I take the car to the Land Rover dealer?

Try disconnecting battery for a couple of minutes and reconnect, a simple reset may clear the problem.
