The Touran Volkswagen screenwasher bottle or reservoir is a container, usually moulded plastic, which sits in the engine compartment and holds between 1-2 litres of screenwash. By activating the screenwash motor a pump will send screenwash from the bottle to the screenwash jets and from there onto the windscreen. The position of the screenwasher bottle in the engine compartment may vary so it may be useful to check the vehicle handbook. The Touran Volkswagen bottle usually has a blue cap and should have a stamp on it showing a graphic of the windscreen wipers with drops of water underneath it. To fill the screenwasher bottle, remove the cap and pour a mixture of screenwash and clean water into the bottle with a jug and funnel until the upper limit is reached.
There is a variety of screenwash available to mix with water when filling the screenwasher bottle. Most Touran Volkswagen will have anti-freeze in to stop the mixture freezing in cold weather and water-softener which will help to keep the plastic tubes and jets clean. All screenwash is specifically formulated to clear road grime, debris and insects from the windscreen.
If your Touran Volkswagen screenwash doesn’t come out of the jets when the stick-lever is operated it can mean that the filter in the screenwasher pump is clogged with debris.
