Is Your Audi S5 Windshield Washer Pump Failing?
A non-functional windshield washer system is more than an inconvenience—it's a safety issue. If your S5's washers aren't working, the pump is a common culprit. Before you assume the pump is bad, check the washer fluid level and make sure the washer nozzles aren't clogged with wax or debris. If those are fine, listen for the pump's humming sound when you activate the washers. No sound usually points directly to a failed pump or an electrical issue, like a blown fuse.
Symptoms of a Bad Washer Pump:
- No Sound, No Spray: You pull the lever and hear nothing but the wipers dragging across a dry windshield. This often means the pump motor has failed or isn't getting power.
- Pump Hums, But No Fluid: If you can hear the pump working but no fluid comes out, the pump's internal impeller might be damaged and unable to create pressure. This can also be caused by frozen fluid, so be sure your system has thawed completely.
- Weak Spray: Fluid barely reaches the windshield. This indicates the pump is losing its ability to generate sufficient pressure and is likely on its way out.
- Leaking Fluid: Puddles of blue or green washer fluid under the front passenger side of your car suggest a leak. The pump itself or its grommet seal can crack and leak over time.
Known Issues & Recalls
While there are no specific recalls for the windshield washer pump on the 2008-2020 Audi S5, searches did identify a Technical Service Bulletin (TSB 92 22 28 2065963/1) for some 2019-2020 models. This TSB addresses a potential leak in the corrugated washer hose inside the cabin, which can cause reduced pressure, a solvent smell, or even electrical issues. This is different from the pump itself failing but can produce similar symptoms. No other widespread, pump-specific recalls were found for this vehicle range.
Choosing a New Aftermarket Washer Pump
When replacing the washer pump on your S5, you have a choice between Original Equipment (OEM) and aftermarket parts. For a simple component like a washer pump, an aftermarket part can offer significant savings without a major compromise in quality.
- OEM (Original Equipment Manufacturer): The genuine Audi part (Part No. 1K6955651) offers a guaranteed fit and performance, but at a premium price, often listed over $100.
- Aftermarket: Brands like Trico and URO Parts provide direct-fit replacements at a much lower cost. For a part like this, which is not a critical engine or safety component, many owners find aftermarket options to be a smart, cost-effective solution.
Brand Focus: Trico vs. URO Parts
Trico is a well-known brand, primarily for wiper blades, but they also offer universal and direct-fit washer pumps. Reviews are generally sparse but positive for their pump products. URO Parts specializes in European car parts and is often a more budget-friendly choice. While some users on forums express caution about using URO for critical components, their simple parts like washer pumps are often considered a reliable, low-cost alternative to expensive OEM parts.

Frequently Asked Questions
Where is the windshield washer pump located on a 2008-2020 Audi S5?
The pump is located at the bottom of the washer fluid reservoir, which is accessed by removing the front part of the passenger-side wheel well liner.
Can I drive my Audi S5 with a broken washer pump?
Yes, but it is not recommended. A non-functioning washer system is a safety hazard, as you cannot clear your windshield of dirt, insects, or road grime, severely impairing visibility. It can also be a violation in some regions that require a functional washer system.
Why did my washer pump fail?
Failure is often due to age and normal wear of the internal electric motor. Using plain water or the wrong type of fluid can lead to freezing in cold climates, which can burn out the motor or crack the pump housing. Using low-quality washer fluid can also cause mineral buildup that leads to premature failure.
Do I need to clear a code after replacing the pump?
In most cases, no. Once the new pump is installed and functional, the system should work immediately. If you had a dashboard warning light for low fluid, it may take a few drive cycles to clear or may clear once the reservoir is refilled and the system is used.
Should I replace the pump grommet at the same time?
Yes. It is highly recommended to replace the small rubber grommet that seals the pump to the reservoir. New pumps often include one. A new grommet ensures a leak-free seal and costs very little.
