Audi RS5 Windshield Washer Pump: A Guide for 2011-2024 Models
Diagnose and replace your failing Audi RS5 windshield washer pump with confidence.
- A silent pump is the #1 sign of failure; listen for the hum in the front passenger wheel well.
- Replacement is a simple DIY job, accessible by removing the passenger-side front wheel and fender liner.
- Aftermarket brands like URO Parts and Trico offer reliable, low-cost alternatives to the OEM pump.
- Always check the fuse first and consider replacing the small rubber grommet with the pump to prevent leaks.
Is Your Windshield Washer Pump Failing?
A bad washer pump on an Audi RS5 is a common issue, but it's usually easy to diagnose. The signs often point directly to the pump itself, an electrical fault, or a simple clog. Before ordering a new part, it's important to confirm the pump is the problem.
Key Symptoms of a Bad Washer Pump
- Pump is Silent: The most obvious sign of failure. You pull the washer stalk, the wipers may move, but you hear no humming sound from the front passenger-side wheel well. This points to a dead pump or an electrical issue.
- Weak or Uneven Spray: If fluid barely reaches the windshield or sprays inconsistently, the pump motor may be dying and unable to create enough pressure. This can also be caused by clogged nozzles.
- Pump Runs, No Fluid: If you can hear the pump motor running but nothing comes out, the reservoir might be empty, the lines could be clogged, or the pump's internal impeller may have failed.
- Fluid Leaks: Puddles of blue or green washer fluid under the front passenger side of your car suggest a leak. This could be from a cracked reservoir or a failed rubber grommet where the pump seals into the tank.
Pro Tip: Check the Simple Things First
Before blaming the pump, check the fuse for the washer system. Also, in freezing weather, ensure your washer fluid hasn't turned to ice, as this can burn out the pump motor. If you recently got a "low fluid" warning that won't go away even after refilling, an Audi TSB suggests that using washer fluid with certain additives can contaminate the level sensor, and cleaning it may resolve the issue.
Choosing the Right Aftermarket Pump: Trico vs. URO Parts
For the Audi RS5, you don't need to pay dealership prices for a reliable washer pump. Aftermarket options provide excellent value for this repair. The two main choices are URO Parts and Trico.
- URO Parts: This is a very common aftermarket brand for European vehicles. URO Parts are known for being a budget-friendly, direct-fit replacement. They are a popular choice for DIY repairs due to their low cost and wide availability.
- Trico: While famous for its high-quality wiper blades, Trico also manufactures washer pumps. They are designed to be an easy-to-install, reliable replacement for the original factory part.
Both brands offer a cost-effective solution. For this specific component, which is a simple electric motor, either brand is a suitable replacement for the original pump.

DIY Replacement Overview
Replacing the washer pump on the RS5 is a manageable DIY job that takes about an hour with basic tools.
- Access the Pump: The pump is located on the washer reservoir, which sits behind the front passenger-side wheel well liner. You will need to safely jack up the vehicle and remove the wheel.
- Remove the Liner: Remove the T25 Torx screws holding the fender liner in place and pull it back to expose the reservoir and pump.
- Replace the Pump: Place a bucket underneath to catch the fluid. Disconnect the electrical plug and the washer fluid hose. The pump simply pulls straight out of a rubber grommet on the reservoir.
- Install New Pump: Press the new pump firmly into the grommet, reconnect the hose and electrical connector, and test the system before putting the liner and wheel back on.
Frequently Asked Questions
My headlight washers work, but not the windshield. Is it the same pump?
No, the Audi RS5 uses a separate pump for the headlight washing system. If one system works and the other doesn't, you only need to replace the pump for the one that has failed. They are often located on the same reservoir.
Are there any recalls for the RS5 washer pump?
No, there are no active recalls from Audi or the NHTSA specifically for windshield washer pump failure on the 2011-2024 Audi RS5.
Do I need to replace the rubber grommet with the pump?
It is highly recommended. The small rubber grommet that seals the pump to the reservoir can become hard and brittle over time, leading to leaks. It is an inexpensive part and good insurance against having to do the job twice.
Could the problem be the switch on the steering column?
While possible, it is very rare for the switch (stalk) to fail compared to the pump motor. If you have a multimeter, you can test for 12V power at the pump's electrical connector when a helper activates the stalk. If you have power, the switch is good and the pump is bad.
