Windshield washer fluid is added to the independent washer fluid reservoir in the engine compartment of the Tiguan L. Pull the engine compartment release handle inside the cabin, open the engine compartment, locate the washer fluid filler port, and add the fluid. The filler cap has a universal symbol resembling a windshield spray. Windshield washer fluid is a cleaning solution for car windshields and is considered a consumable in automotive use. Its main components include water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. There are several types of windshield washer fluids: Summer type, which contains insect remover additives to quickly eliminate insect residue on the windshield; Winter antifreeze type, which ensures it won't freeze or damage car components even at temperatures below -20°C; and Special antifreeze type, which remains unfrozen at -40°C, making it suitable for extremely cold regions. Automotive windshield washer fluid is widely used for quick cleaning and brightening of car windows, rearview mirrors, household glass, office glass, door and window glass, and decorative glass. It offers comprehensive performance, is easy to use, and can even be homemade. It provides cleaning, antifreeze, antifog, antistatic, lubrication, and anticorrosion properties.

I've been driving the Tiguan L for several years, and its windshield washer fluid filler is located in the engine compartment, generally near the front on the driver's side. The specific method is: first, open the hood release lever inside the cabin, pull it, and the hood will pop open slightly. Walk to the front of the car and lift the hood to find a small blue cap on the right side of the engine compartment, marked with a windshield and washer symbol, shaped like a spray bottle. It's recommended to use antifreeze washer fluid, especially in winter, to prevent freezing and nozzle blockage, and to help the wipers clean the windshield efficiently. The fluid level should usually reach the indicator line below the cap—avoid overfilling to prevent spillage. I make it a habit to check monthly and top up before long trips to ensure the wipers function smoothly.

When adding windshield washer fluid to the Touareg L, the location is quite simple under the hood. Once the hood is opened, you can easily find the blue-capped reservoir, typically positioned at the front-left of the engine bay, clearly marked with a windshield wiper icon. This spot can be confusing with other components, such as the coolant reservoir, but the icon makes it unmistakable. Remember to use a standard washer fluid mixture, not just plain water, to avoid freezing and system damage in winter. I advise everyone to keep the reservoir full—running out of fluid during rainy weather can be a major hassle and compromise driving safety.

I previously bought a Tiguan L and couldn't find where to add windshield washer fluid the first time. It's located in the engine compartment, near the engine, with a cap marked by water ripples or a spray symbol. Just open the cap and fill it with cleaner, usually about one liter in capacity. Refill it promptly when the level is low to ensure proper spraying. This method is simple and effective, with no technical difficulties.
