Is Your Audi TT Windshield Washer Not Working?
If you activate your windshield washers and nothing happens, a failed pump is the most likely cause. On the 2011-2018 Audi TT, this is a common point of failure as the vehicle ages. The primary job of this pump is to get cleaning fluid onto your windshield, a critical function for safe driving in all conditions. Understanding the symptoms of a bad pump can help you decide if it's time for a replacement.
Symptoms of a Failing Washer Pump
Diagnosing a bad washer pump on your TT is usually straightforward. Look for these common signs:
- No Sound, No Spray: The most definitive symptom is complete silence when you try to use the washers. You should normally hear a distinct whirring or humming sound from the front of the car as the pump operates. If you hear nothing and no fluid comes out, the pump motor has likely failed.
- Pump Makes Noise, But No Fluid Sprays: If you can hear the pump running but no fluid reaches the windshield, the issue might be a clog in the system, a disconnected hose, or frozen fluid in the lines during cold weather. It's also possible the pump is weak and lacks the pressure to push fluid to the nozzles.
- Low Washer Fluid Warning Light: While this usually means you just need to add fluid, a faulty pump or a leak in the system (sometimes from a cracked pump housing) can also be related. Some owners have noted a general "washer system fault" message on the dashboard.
A Note on Cold Weather
Washer pumps can fail suddenly, and many owners report failures occurring on cold mornings. Using a washer fluid with an appropriate antifreeze rating for your climate is crucial. If water or a low-quality fluid freezes in the pump, it can cause the motor to burn out or the housing to crack.
Choosing a Replacement Pump: OEM vs. Aftermarket
When replacing the washer pump on your Audi TT, you have two main choices: a Genuine Audi (OEM) part or an aftermarket part from a brand like Trico.
- OEM (Original Equipment Manufacturer): An OEM pump is the same part your car was built with. It guarantees a perfect fit and is known for good longevity, with original pumps often lasting many years. However, it is the more expensive option.
- Aftermarket (Trico): Aftermarket brands offer a more affordable solution. A brand like Trico produces pumps designed to fit a wide range of vehicles, including the Audi TT. While the quality is generally good for the price, some user experiences suggest they may not last as long as the OEM version. For a simple part like a washer pump, an aftermarket option is a very practical and cost-effective choice for many owners.
Pro Tip: Check the Grommet
The pump seals to the reservoir with a rubber grommet. It's best practice to replace this grommet when you replace the pump to prevent leaks. Some replacement pumps include a new grommet, but be sure to check.

Frequently Asked Questions
Is replacing the washer pump a DIY job?
Yes, for those with basic mechanical skills. The job requires jacking up the front of the car, removing a wheel and the plastic wheel well liner to get access to the washer reservoir. The pump itself just pulls or twists out. The entire process can often be done in under an hour.
Are there any recalls for the Audi TT washer pump?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no safety recalls for the windshield washer pump on the 2011-2018 Audi TT.
Do I need to drain the washer fluid to replace the pump?
Yes. The pump is located at the bottom of the reservoir. If you remove it without draining the tank first, all the fluid will spill out. It's best to either run the system dry (if possible) or have a catch pan ready and let it drain when you pull the old pump out.
Does this one pump operate both the front and rear washers?
On many vehicles that use this common VAG pump, it is a dual-outlet pump that services both front and rear windshields. However, your TT may have separate pumps for different functions (e.g., headlight washers). When ordering, ensure the pump matches the function you are replacing.
