Pretty often I get the low washer fluid warning. Topped it up, didn’t use it, and again the warning. The warning comes while driving on the motorway, or after 10 minutes when stopping at a junction. I would expect this message every time I start the engine, but that is not the case.
It does not leak, so it seems a false warning caused by what? Any suggestions where to start looking?

I'm pretty certain there's a sensor on the tank. If I remember correctly it's actually the same as the one on the coolant tank

@waldorf Well done for getting it sorted!!

Is that a scrap bit of flooring you're using? Thats a great idea!
