Mercedes-Benz | How To Fix Faulty Washer Fluid Warning

How to fix faulty washer fluid warning (Top up washer fluid) for Mercedes-Benz E-Class W212 and many other models and cars use the same system. Really annoying problem because its only let me use mb genuine washer fluid and they are really expensive for the winter fluid that can withstand minus 25 degrees and only online order.

Think this procedure working really good and its easy to restore for summer when its not showing this kind of warnings because summer fluid got more water. But if you really tired to keep messing with this sensor you could connect the wires and forget about this thing : )

Mercedes WinterFit (part-nr A002986147109) fluid cost about 7€ per liter then I can pour in one liter water in that so about 3,5€ per liter washer fluid that's about same cost I pay for 4 liter non mb fluid. If that's been all but got no mb dealer here that's mean I had to order it online with shipping 20€ each time.

Mercedes SummerFit (Part-nr A001986807117) its another history its 4€ for 40ml concentrate that can be used to 4L water only about 1€ per liter.
