Audi A3 Quattro Windshield Washer Pump Guide (2015-2020)
Is your Audi A3's washer fluid not spraying? This guide covers common symptoms, replacement costs, and how to choose the right aftermarket pump.
- A single dual-action pump services both the front and rear windows; failure of one can indicate the need for replacement.
- Accessing the pump is done through the passenger-side wheel well or by removing the fog light grille, which is easier than removing the whole bumper.
- Before replacing the pump, always check for simple fixes like a blown fuse, clogged nozzles, or an empty reservoir.
- Premium aftermarket brands like Vemo offer OEM-like quality for less, while brands like URO are a budget-friendly alternative.
Is Your Audi A3 Quattro Washer Pump Failing?
A non-working windshield washer can be a safety issue, especially during bad weather. For the 2015-2020 Audi A3 (8V generation), the washer pump is a common wear-and-tear item. When it fails, you might hear nothing when you pull the stalk, or you might hear the pump whirring with no fluid coming out. This guide will help you diagnose the problem, choose the right replacement part, and understand the repair process.
Common Failure Symptoms
Before you buy a new pump, make sure you need one. Here are the most common signs of failure:
- No Spray from Nozzles: The most obvious symptom. If the reservoir is full and you hear no motor sound when you activate the washer, the pump itself or its fuse is the likely culprit.
- Pump Motor Runs, But No Fluid Sprays: If you can hear the pump motor humming but no fluid comes out, the problem could be a clogged filter at the pump's intake, blocked nozzles, or a leak in the washer fluid lines. A TSB for other Audi models notes that washer hoses can rupture inside the cabin.
- Weak or Inconsistent Spray: A dying pump may lose its ability to generate strong pressure, resulting in a weak stream that doesn't effectively clean the windshield.
- Front or Rear Works, But Not Both: Since the A3 uses a dual-function pump, a failure in one direction can indicate an internal problem with the pump motor's reversing capability.
- Blown Fuse: Sometimes a failing pump motor can short out and repeatedly blow the corresponding fuse.
Check the Simple Things First
Before ordering a new pump, check that your washer fluid reservoir is full. Also, check for a blown fuse, which is a common and easy fix. 🎬 Watch this video to learn how to diagnose your washer system. Finally, use a small pin to gently clear any debris from the washer nozzles on the hood.
Choosing the Right Aftermarket Washer Pump
You don't need to buy an expensive OEM pump from the dealer. Quality aftermarket brands offer a reliable and affordable alternative. The brands available in our inventory—Trico, URO Parts, and Vemo—represent different tiers of the aftermarket.
- Good (Economy): URO Parts
URO Parts is a budget-friendly option. While they make a wide range of parts, community feedback suggests their quality can be inconsistent, particularly for complex electronic or rubber components. For a simple part like a washer pump, it can be a cost-effective choice, but may not have the longevity of higher-tier brands. - Better (Standard): Trico
Trico is a well-known leader in wiper technology and offers OE-style replacement washer pumps. Their pumps are designed for easy installation and are a solid, reliable choice for a daily driver, often balancing cost and quality effectively. - Best (Premium): Vemo
Vemo is a German brand often considered a premium aftermarket supplier, sometimes even providing parts for original equipment. Choosing a Vemo pump generally means getting a high-quality part with excellent fit and durability, making it a smart choice for owners who prioritize longevity and performance.
Cost of Replacing Your Audi A3 Washer Pump
The cost to replace the washer pump varies depending on whether you do it yourself or take it to a shop. The part itself is inexpensive, but labor can add up as accessing the pump can be time-consuming.
| Part/Service | Estimated Cost |
|---|---|
| New OEM Pump | $45 - $114 |
| New Aftermarket Pump | $13 - $38 |
| Shop Labor | $102 - $149 |
| Total Professional Repair | $147 - $263 |
DIY Installation Tip
The washer pump is located at the bottom of the fluid reservoir, behind the front bumper on the passenger side. While some guides suggest removing the entire front bumper, many owners have found an easier way. By removing the front passenger wheel and the fender liner, or even just the fog light grille, you can often gain enough access to swap the pump. This can turn a difficult job into one that's manageable for a DIYer in about an hour. 🎬 See this walkthrough for the easiest way to swap the pump. Always have a bucket ready to catch the washer fluid when you pull the old pump out!
Frequently Asked Questions
Are there any recalls for the 2015-2020 Audi A3 washer pump?
No, there are no specific recalls for the windshield washer pump on the 2015-2020 Audi A3 Quattro. However, a Technical Service Bulletin (TSB) was issued for a related issue where the washer fluid level sensor gives a false warning; this is typically caused by fluid additives and is fixed by cleaning the sensor probes.
Is the front and rear washer pump the same part?
Yes, for the Audi A3, a single "dual pump" is typically used for both the front and rear washers. The pump changes the direction of flow by reversing its motor's polarity, which is controlled by the vehicle's body control module when you select the front or rear washer function.
Do I need to drain the washer fluid to replace the pump?
The pump is located at the bottom of the reservoir, so when you remove it, any fluid inside will drain out. It's best to either run the pump until the reservoir is empty (if possible) or have a container ready to catch the fluid. This is also a good opportunity to clean the reservoir and the pump's filter screen.
Why do I hear the new pump running but nothing sprays?
If you've installed a new pump and can hear it working, the issue is likely a blockage elsewhere. First, check that the hoses are connected correctly to the pump's outlets. Second, check for clogs in the lines or at the spray nozzles themselves. In rare cases, an electrical issue could cause the pump to run but not generate enough pressure.
