Audi A3 Windshield Washer Pump: A Guide for 2006-2020 Models
Everything you need to know before replacing the windshield washer pump on your 2006-2020 Audi A3.
- A single dual-action pump typically operates both front and rear washers; failure of one direction requires replacing the whole pump.
- Access is through the front passenger wheel well, often requiring removal of the fender liner.
- No specific recalls or TSBs were found for this part; failure is typically due to age and wear.
- Always replace the rubber grommet with the pump to prevent leaks.
Is Your Audi A3 Washer Pump Failing?
A non-working washer system is often caused by a bad pump. The first step is to make sure your washer fluid reservoir is full. If it is, and you don't hear the pump's whirring sound when you try to use the washers, the pump itself is the most likely problem. Another common issue is clogged nozzles, but if both front and rear washers stop working at the same time, a failed pump is a strong possibility.
Symptoms of a Bad Windshield Washer Pump
- No fluid spray: No washer fluid sprays onto the windshield or rear window.
- No sound: You don't hear the familiar humming or whirring noise from the pump when you activate the washers.
- Weak spray: The fluid barely reaches the glass, indicating the pump is losing pressure.
- Front works but rear doesn't (or vice-versa): On dual-action pumps, one side can fail while the other still works. This points directly to a faulty pump rather than a fuse.
Check for Leaks
Before ordering a new pump, check for leaks. A puddle of washer fluid under the front passenger side of the car could mean a cracked reservoir or a bad seal where the pump enters the tank. These should be addressed during the replacement.
Choosing the Right Aftermarket Pump
When replacing the washer pump on your A3, you don't have to buy an expensive OEM (Original Equipment Manufacturer) part from the dealer. Aftermarket parts offer significant savings. The brands are generally grouped into tiers based on quality and price.
- Vemo: Often considered a higher-tier aftermarket brand, Vemo parts are known for good quality and fit, sometimes even being the original supplier for certain components. They are a solid choice for a reliable, long-lasting replacement.
- Trico: Trico is a well-known brand in wiper and washer systems. Their pumps are designed for easy installation and are made from durable plastic, offering a reliable, mid-range option.
- URO Parts: URO Parts provides budget-friendly alternatives. While they can be a good value, quality can sometimes be inconsistent compared to higher-priced brands. They are a viable option if cost is your primary concern.
Pro Tip: Replace the Grommet
The small rubber seal, or grommet, where the pump pushes into the reservoir often becomes brittle and leaks. Always replace the grommet when you install a new pump to prevent future leaks. It's an inexpensive part that can save you a lot of trouble.

The washer pump is located at the bottom of the washer fluid reservoir. On the Audi A3, this reservoir is positioned in the front passenger-side wheel well, behind the bumper cover. 🎬 See how to find the hidden washer pump location here. While some mechanics remove the entire front bumper, many find that you can access the pump by removing the passenger-side front wheel and the plastic fender liner. On some models, removing the fog light grille and the fog light itself can provide direct access to the pump without removing the fender liner.

Frequently Asked Questions
Do I need to replace the front and rear pump?
Most 2006-2020 Audi A3 models use a single dual-outlet pump that serves both the front and rear washers. The pump reverses polarity to send fluid to the correct set of nozzles. If either the front or rear stops working, you will replace the entire pump unit.
Are there any recalls for the Audi A3 washer pump?
Based on searches of the NHTSA database and other public records, there are no specific recalls for the windshield washer pump on the 2006-2020 Audi A3.
How do I test the washer pump before replacing it?
First, check the fuse. If the fuse is good, you can use a multimeter to check for power at the pump's electrical connector when a helper activates the washer switch. If you have power and ground but the pump doesn't run, the pump has failed.
Why did my new aftermarket pump stop working?
Early failure is rare but can happen. It could be a defective part or an electrical issue. One common cause of pump failure is running the system dry. The fluid acts as a coolant for the pump motor, so running it without fluid can cause it to overheat and burn out. Always ensure your reservoir is topped off.
