What are the reasons for the Audi Q3 wiper not spraying water?

If no water comes out when operating the switch, it may be frozen due to cold weather. You can try again at noon when it's warmer. The car components that may cause weak or no water spray are: Windshield washer reservoir, washer fluid, water hose, washer pump, filter screen, and spray nozzles. The reasons for weak or no water spray include: Low washer fluid level; Leaking water hose - for example, the hose may have been bitten through by rodents or the hose connection may have come loose. Clogged filter screen - mainly caused by using inferior washer fluid or tap water, which is a cumulative process. When most of the filter screen is clogged, it's like pressing the intake side of a water pump - it becomes very difficult to pump, same principle here; Clogged spray nozzles - possibly caused by waxing the windshield which may have covered the nozzles; Frequent use of inferior washer fluid or direct use of tap water; Damaged washer pump or electrical circuit failure.
I've been driving an Audi Q3 for a while and noticed the wipers aren't spraying water, possibly because the washer fluid reservoir is empty. I've experienced this myself—in winter, not adding antifreeze in time caused the water to freeze and the nozzles to clog. Quickly check the water level, add water, and wait for it to melt or rinse the nozzles with warm water. If the water pump is broken, listen for a humming sound; if there's none, it might be a motor failure or a blown fuse. Usually, you can find the corresponding headlight washer fuse in the engine compartment fuse box and replace it. Wiring issues, like rodents chewing through wires or loose connectors, are also common—try simply pushing the connector tight. It's best to keep a small toolkit handy and regularly clean the nozzles to prevent dirt buildup, ensuring a clearer windshield and safer driving. Regular checks can save a lot of trouble—don't wait until rainy days when visibility is poor to address it. Audi systems are stable, but basic maintenance shouldn't be neglected.
The common causes of windshield washer failure on the Audi Q3 are aging of the water pump motor or clogged nozzles. My car has been driven for several years, and the nozzles were once completely blocked by dust, which was resolved by slowly poking through with a fine needle. A malfunctioning water level sensor may fail to alert when the reservoir is empty, so try filling it with dedicated windshield washer fluid. Leakage in the system's piping or valve failure could lead to pressure loss; check for signs of water seepage at pipe joints. In cold regions, windshield washer fluid can freeze and expand, damaging the pump, so opt for a low-temperature antifreeze model as a preventive measure. Electrical issues such as a blown fuse or poor contact in the control switch can be checked at a professional shop using a multimeter to measure current. Don't overlook these details during maintenance—Audi's precision engineering means small issues are easily fixable, but addressing them early prevents blurred vision while driving.
