Your 1999-2010 Audi TT Windshield Washer Pump: A Complete Replacement Guide
If your washers are dead but the fluid is full, the pump is the most likely problem.
- The most common sign of failure is no sound from the pump and no fluid spray when activated.
- Replacement is a simple DIY task that takes under an hour and is accessed through the passenger-side wheel well.
- Aftermarket brands like URO Parts and Trico offer significant savings over the OEM part and are effective replacements.
- When replacing, ensure the new pump includes a new rubber grommet to prevent future leaks.
Is Your Audi TT Washer Pump Failing?
A failing windshield washer pump on the 1999-2010 Audi TT is a common issue, but it's usually simple to diagnose. The most obvious sign is when you activate the washers and nothing happens. If you don't hear the familiar whirring or humming sound of the pump motor, and you know the fluid reservoir is full, the pump has likely failed.
Common Failure Symptoms:
- No Sound, No Spray: You pull the lever, the wipers move, but you hear no pump motor sound and no fluid sprays on the glass. This is the most common symptom of a dead pump.
- Weak Spray: The fluid barely reaches the windshield or just dribbles out of the nozzles. This can mean the pump motor is getting weak and losing its ability to create enough pressure.
- Pump Runs, No Spray: If you can hear the pump motor running but no fluid comes out, the problem might be a clogged or disconnected hose, or the pump's internal impeller could be broken.
- Fluid Leaks: Puddles of washer fluid under the front passenger side of the car can point to a cracked pump housing or, more commonly, a failed rubber grommet where the pump seals to the reservoir.
Check Your Fuses First
Before ordering a new pump, always check the fuse for the washer system. On the Audi TT, the washer pump often shares a fuse with other components. Consulting your owner's manual for the correct fuse location and checking it can save you time and money.
Choosing the Right Aftermarket Pump
When replacing the washer pump on your TT, you don't need to pay high dealer prices for an Original Equipment (OEM) part. Aftermarket pumps offer a cost-effective and reliable solution. The two main types you will find are direct-fit replacements and universal pumps.
- Direct-Fit Pumps: These are designed to be identical to the factory part for an easy installation.
- Universal Pumps: These may require minor modifications to the wiring or mounting to fit. For a straightforward repair, a direct-fit pump is recommended.
Aftermarket Brand Quality: Trico vs. URO Parts
For the Audi TT, both Trico and URO Parts are common aftermarket options.
- URO Parts: This brand specializes in parts for European vehicles like Audi and is often seen as a direct, budget-friendly alternative to genuine parts. They are widely available and many owners use them for repairs.
- Trico: Trico is a well-known brand in the general automotive world, recognized for making easy-to-install replacement parts like wiper blades and washer pumps. While reviews are positive for other vehicles, they are less specifically mentioned in Audi forums.
Both brands provide a functional replacement for a fraction of the OEM cost. The most important factor for a successful repair is ensuring the pump comes with a new rubber grommet (seal), as this is a common failure point that causes leaks.
Pro Tip: Clean the Reservoir
While the pump is removed, take the opportunity to clean any gunk or debris from the bottom of the washer fluid reservoir. Old fluid and contaminants can clog the filter screen on the new pump and cause it to fail prematurely. Some owners also report that using washer fluids with additives like water repellents can damage the pump over time.
Cost of Replacing an Audi TT Windshield Washer Pump
Replacing the washer pump is an affordable repair, especially if you do it yourself. The part itself is inexpensive, and labor at a shop should be minimal.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Pump | $13.87 - $37.72 |
| New OEM (Dealer) Pump | $90 - $110 |
| Shop Labor | $60 - $120 |
Frequently Asked Questions
Where is the washer pump located on a 1999-2010 Audi TT?
The windshield washer pump is located at the bottom of the washer fluid reservoir. You can access it by removing the front passenger-side wheel and the plastic wheel well liner.
Is this a difficult repair to do myself?
No, this is considered a simple DIY job for someone with basic hand tools. The process takes about 30-60 minutes and mainly involves removing the wheel liner for access.
Do I need to drain the washer fluid first?
The fluid will drain out when you remove the pump from the reservoir. Be sure to have a bucket or drain pan ready to catch it to avoid a mess.
My low fluid warning light is on, but the tank is full. Is that the pump?
No, that is likely an issue with the washer fluid level sensor, not the pump. An Audi Technical Service Bulletin (TSB) notes that certain washer fluid additives can coat the sensor and cause false readings. The sensor is a separate part from the pump.
