How to fix top up washer fluid
It seems that Mercedes has some sensor that not can detect all kind of washer fluids. Have read on the web that its seems only to happen with winter fluids!?
My light has been on since I bought the car always go with - 30 Celsius and didn't know why that message keep popping up all the time. Was reading here on the forum some say it can be the fluid and yess it was.
If you have the same problem you may try to change your fluid.

I rarely use fluid, just a gallon of distilled water (easy on the nozzles) and a squirt of Dawn dishwashing liquid. The Dawn has enough electrolytes in it to allow the conductors of the level sensor to work properly. If you're in a colder climate add some ammonia or rubbing alcohol to lower the freezing point.

You're only supposed to use the blue MB fluid. I've already replace my sensor. When you use the wrong fluid, it can gum up the sensor so that it's on all the time no matter what you use. But the sensor is only around $10+ and not too hard to change out. No idea what the previous owner used.

Now I see it leaking from underside common problem it’s the grommets to the pumps they are 2 pumps in the bottom and you access these from the front tire housing!
Here you got MB art-nr if you have same issue!

I had the washer tank grommets leaking on my 2001 ML when I bought it in 2008.
My remedy was to go to JY and remove the same size grommets from MB build in 1980's as those last for decades.
Same for hose and wire holders.

No, the latest level sensors are not float sensors, but conductivity sensors.
They need certain PH, or whatever for current flow and not all fluids provide it.
That's where 3 grains of salt make the difference.

Hi. I’ve had the same problem last winter. What happened is I used some orange -45 fluid bought at Canadian tire. I’m in Canada. 
. And the problem started. I’ve heard about the issues like that before somewhere on the forum. I run the orange fluid out which took few min of window washing. Anyways. I bought another brand and never had a problem. My fluid is blue now.

The 3 salt grains remedy is something I pick up from respectful member on Polish MB forum and it only makes sense.
Coming to technical application, I can't verify size of Polish grains v/s USA grains, so you have to do your own experiment ..

I have used various washer fluids from very many different gas stations and Walmart where it is cheap. I have never seen any problem with the washer tank level. When it says "Check washer fluid" I stop at a gas station and buy and pour a gallon of washer fluid in the reservoir. Never had any problem and never thought I would have to buy washer fluid from the dealer. That would be insane. Something else is wrong, not the fluid.

Just normal "clean" water conducts electricity and I believe all washer fluids have water in it so hard to believe this would be a fluid issue.

It's like a $10 sensor, basically just two metal probes with an electrical connector. I wouldn't exactly call that fancy. In other cars, you know you're out when nothing comes out.
