How much windshield washer fluid should be added to the Tiguan L at one time?

[McIsabelle]

Tiguan L generally requires 2 liters of windshield washer fluid per refill. The Volkswagen Tiguan L has a windshield washer fluid capacity of 5L, so you can add an appropriate amount based on the remaining level. Windshield washer fluid is only consumed during use and doesn't have a fixed refill cycle - simply refill when running low. Windshield washer fluid, also known as car windshield cleaning liquid, is a consumable automotive product. Its main components include water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. There are three main types of windshield washer fluid: 1) Summer type, which contains insect removal agents to quickly clean insect residues from the windshield; 2) Winter antifreeze type, which prevents freezing and damage to car components even when temperatures drop below -20°C; 3) Special antifreeze type, which remains unfrozen at temperatures as low as -40°C, making it suitable for extremely cold regions.
