Washer bottle sensor

[vroomtshh]

Strange question - My windscreen washer bottle appears to have a sensor fitted (top of the bottle, sensor with convoluted tubing running from it)
But when my bottle runs empty, I get no warning.

I'm about to do the full DIS upgrade, and I was waiting to see if my sensor worked. Is there any way for me to check that whats there works?

The sensor for low fluid sits in the bottom section of the washer bottle, if you remove the passenger wheel arch lining you will see it....
