Hi guys new to this forum! Driving a Mercedes W212 E-Class and since I bought the car the washer fluid warning keep coming on even when the reservoir is full. Searching the web and some say it only happen when they use fluid for colder climate, and it seems to be correct some fluid works some not. Have use the same fluid to - 30 always and that's why it keep warning about low fluid.
Today I did a test and it seems to work! Hope it help you!
