Why can't the windshield washer fluid be added to the BMW 3 Series?

[DeAliyah]

BMW 3 Series windshield washer fluid cannot be added because it is internally blocked and needs to be cleaned; or the previously added washer fluid had a higher freezing point, and when entering an area with temperatures below zero, the washer fluid froze. Characteristics of windshield washer fluid: Windshield washer fluid is commonly known as car windshield cleaning fluid and is a consumable for automobiles. It is composed of water, alcohol, ethylene glycol, corrosion inhibitors, and surfactants. When using the wipers to clean the car windshield, the window becomes brighter and cleaner, providing the driver with an excellent driving view. Precautions for windshield washer fluid: There are many details to pay attention to when using car windshield washer fluid. In winter, it is necessary to place the washer fluid inside the car first before adding antifreeze washer fluid. Do not use tap water as a substitute for washer fluid. Tap water contains various impurities. Long-term use of tap water as washer fluid can clog the washer fluid pipes, damage the wiper motor, and cause the wipers to malfunction.
