Guide to the 2005-2011 BMW M6 Windshield Washer Pump
Having trouble with your washer fluid spray? Here’s what you need to know before replacing the pump on your E63 or E64 M6.
- The most common cause of failure is a clogged filter, not the pump itself. Diagnose by listening for the pump motor.
- Replacement is a straightforward DIY job, requiring access through the front passenger wheel well.
- Always replace the rubber grommet/filter when replacing the pump to prevent future clogs and leaks.
- Aftermarket brands like URO Parts offer a cost-effective and reliable solution for this specific component.
Symptoms of a Failing Windshield Washer Pump
When the washer pump in your M6 begins to fail, the signs are usually obvious. The most common issue is not the pump itself, but a clogged filter. Here’s what to look for:
- No Fluid Spray: You pull the stalk and hear nothing, and no fluid comes out. This often points to a failed pump motor or an electrical issue.
- Weak or Low Spray: The fluid barely reaches the bottom of the windshield. This is a classic sign of a clogged pump filter or a dying pump motor.
- Pump Sound Changes: If you can hear the pump motor running but no fluid sprays, the filter is almost certainly clogged with debris or algae-like buildup from using incorrect washer fluid.
- Leaking Fluid: Puddles of blue or green fluid under the front passenger side of the car indicate a leak. This can come from a cracked pump housing or, more commonly, a dried-out and brittle rubber grommet where the pump enters the reservoir.
Pro Tip: Diagnose Before You Buy
Before ordering a new pump, have a friend activate the washers while you listen near the front passenger-side wheel well. If you hear a humming sound, your pump motor is working. The problem is likely a clogged filter grommet, which is a much cheaper part to replace first. If you hear nothing, the pump itself has likely failed.
Choosing the Right Aftermarket Part
For a component like the windshield washer pump, an aftermarket part offers significant savings compared to a Genuine BMW part, which can cost over $60. The aftermarket options for this part are generally considered reliable for their intended function. The key is choosing a brand that fits well and lasts. Your two main options are Trico and URO Parts.
Brand Quality: Trico vs. URO Parts
- URO Parts: URO is a well-known aftermarket brand that offers budget-friendly parts for European vehicles. For a simple part like a washer pump, it is generally considered a reliable choice that provides proper fit and function. Many DIY guides and forums suggest that for non-critical components, URO provides excellent value. It is highly recommended to also purchase a new rubber grommet/filter when installing a URO pump.
- Trico: While famous for its wiper blades, Trico also manufactures washer pumps. These are often designed for easy installation and may be a universal or semi-universal fit, sometimes requiring no special adjustments. There is less specific feedback from BMW owners on Trico pumps, but they are a reputable brand in the automotive aftermarket.
| Part | Cost Range |
|---|---|
| New OEM | $60 - $90 |
| New Aftermarket (Trico, URO Parts) | $15 - $40 |
| Shop Labor | $150 - $250 |
Installation Overview
Replacing the washer pump is a manageable DIY project for those with basic tools. The pump is located in the front passenger-side wheel well, pushed into the bottom of the washer fluid reservoir.
- Safely jack up the front passenger side of the vehicle and remove the wheel.
- Remove several 8mm screws holding the front section of the plastic fender liner and peel it back to access the reservoir.
- Place a bucket underneath to catch any remaining washer fluid.
- Disconnect the electrical connector and the fluid hose from the old pump.
- Firmly pull the old pump out of the rubber grommet on the reservoir.
- Remove the old rubber grommet and clean the area. Install a new grommet.
- Push the new pump firmly into the new grommet, reconnect the hose and electrical plug, and test the system before reassembling.
Common Mistake: Reusing the Old Grommet
Always replace the rubber grommet/filter when you replace the pump. This part is often the true source of the problem, either from being clogged or from being old and brittle, causing leaks. Most aftermarket pumps do not include a new one, so be sure to order it separately.
Frequently Asked Questions
Is this a difficult DIY job?
For most home mechanics, this is a relatively easy job. It requires jacking up the car and removing a wheel, but the pump replacement itself is straightforward. The entire process typically takes 1-2 hours.
Do I have to use special BMW washer fluid?
While not strictly required, it is highly recommended. Using unapproved fluids or straight tap water can cause algae-like substances to grow in the reservoir, which is the number one cause of clogged pump filters. Sticking to a quality, name-brand fluid designed for European cars is your best bet.
Does the M6 have one or two washer pumps?
The E63/E64 M6 has two separate pumps in the washer reservoir. There is a low-pressure pump for the windshield and a high-pressure pump for the headlight washers. Make sure you are ordering the correct pump for the windshield.
My pump is running, but the spray is weak. Is the pump bad?
Not necessarily. If you can hear the pump motor, the most likely cause is a clogged filter screen on the grommet where the pump enters the reservoir. Try cleaning or replacing the grommet/filter first before spending money on a new pump.
