How to Replace 2017 Audi A4 Windshield Wipers

To replace the windshield wipers on a 2017 Audi A4, lift the wiper arms into service position, release the old blades from their connectors, and clip in new blades of the correct size before returning the arms to the windshield. The process is straightforward if you use the proper wiper sizes, follow the car’s service-mode procedure, and handle the arms carefully to avoid cracking the glass.

Understanding Your 2017 Audi A4 Wiper System

The 2017 Audi A4 uses an aero-style wiper system with low-profile blades designed to improve visibility at speed and in bad weather. Knowing how the system is built and what parts you need helps ensure a safe, clean installation.

Wiper Sizes and Types

For the 2017 Audi A4 (B9 generation), the front wiper blades are two different lengths, and the car does not use a rear wiper because it is a sedan. Choosing the correct lengths and type of blade is essential for proper sweep and pressure distribution.

The following list describes the typical blade sizes and types recommended for the 2017 Audi A4.

• Driver’s side blade: Approximately 24 inches (600 mm), aero/beam-style blade.
• Passenger’s side blade: Approximately 20 inches (500 mm), aero/beam-style blade.
• Blade style: Direct-fit beam (aero) blades, often sold as “OEM replacement” or “vehicle-specific” for Audi A4 2017.
• Connector type: Most replacements use a vehicle-specific OE-style connector or a multi-adapter system compatible with Audi’s front wiper arms.
• Recommended brands: OEM (Audi/VW), Bosch, Valeo, Trico, or Michelin lines that explicitly list compatibility with 2017 Audi A4.

Checking the wiper size guide on a reputable parts site or the Audi parts catalog is wise before buying, as different body styles and markets can sometimes vary slightly.

When to Replace the Blades

Windshield wiper performance directly affects visibility, especially in heavy rain or winter conditions. The 2017 Audi A4’s blades are designed to last, but they are still wear items that should be checked regularly.

The following list outlines key signs that your 2017 Audi A4 wiper blades need replacement.

• Streaking or smearing: Water is left behind in long streaks, even after repeated passes.
• Chattering or skipping: Blades bounce or judder across the glass instead of gliding smoothly.
• Cracked or split rubber: Visible cracks, tears, or separation along the wiping edge.
• Uneven contact: Sections of the windshield stay wet, especially near the edges or center arc.
• Noise: Squeaking or scraping sounds even on a wet windshield.
• Age: More than 6–12 months in harsh climates (hot sun, freezing winters), or 12–18 months in milder conditions.

Replacing the blades as soon as these symptoms appear can prevent strain on the wiper motor and safeguard visibility during sudden downpours or snow.

Tools, Parts, and Preparation

Before you start, assembling the right tools and parts makes the replacement faster and reduces the risk of damaging the windshield or wiper arms.

What You Need

The replacement job is simple and usually requires no complex tools, but a few items will help protect your car and make installation easier.

The following list details the basic items you should gather before replacing the wipers on a 2017 Audi A4.

• New wiper blades: One driver’s side and one passenger’s side blade, sized and specified for 2017 Audi A4.
• Soft towel or foam pad: To place on the windshield as protection if the wiper arm springs back.
• Gloves (optional): To improve grip and keep oils off the rubber blade.
• Owner’s manual: For reference on wiper “service position” and any Audi-specific notes.
• Mild glass cleaner and microfiber cloth (optional): To clean the windshield and improve wiping performance after installation.

Once you have these items ready, you can proceed smoothly through the replacement without needing to pause for missing tools or protective materials.

Putting the Wipers into Service Position

On many modern Audis, including the 2017 A4, the wipers park low and partially hidden under the hood line. To change the blades safely and comfortably, Audi provides a “service position” that raises the arms.

The following list explains the typical steps for engaging the wiper service position on a 2017 Audi A4.

1. Turn on the ignition: Press the start button once without pressing the brake, or turn the key to the accessory/on position so electronics are powered.
2. Switch the wipers off completely: Make sure the wiper stalk is in the “off” position.
3. Turn off the ignition: Switch the car off fully.
4. Operate the wiper stalk: Within a few seconds of shutting off the ignition, push the wiper stalk down briefly (as if giving a single wipe). The wipers should move up and stop in a vertical service position on the windshield.
5. Confirm position: The blades should now sit high enough on the glass to allow the arms to be lifted away from the windshield.

This service position reduces the risk of hitting the hood edge and gives you enough clearance to remove and install the blades without fighting the cowl or bodywork.

Step-by-Step: Replacing the Front Wiper Blades

With the arms in service position, you can swap out the old blades for new ones. The process is similar for driver and passenger sides, but always handle each arm as if the glass beneath it is unprotected and vulnerable.

1. Lift the Wiper Arm and Protect the Glass

The first physical step is to lift each arm off the windshield and prepare for any accidental slips. The spring-loaded arms can snap back quickly if released.

The following list details how to safely position the wiper arm and protect your windshield.

1. Lift the arm: Gently pull the wiper arm away from the windshield until it locks or rests in a raised position.
2. Place a towel or pad: Lay a folded towel or foam pad on the windshield under the raised arm to cushion it if it snaps back.
3. Support the arm: Hold the arm with one hand while working with the other; avoid letting it dangle freely.
4. Work on one side at a time: Replace the driver’s blade completely before moving to the passenger side to prevent confusion and mix-ups.

Taking a moment to protect the glass and support the arm lowers the risk of an accidental crack or chip if the metal arm slams against the windshield.

2. Remove the Old Wiper Blade

Most 2017 Audi A4s use an OE-style connector that clips the blade to the arm. It usually involves depressing a tab and sliding the blade out along the arm’s channel or hook.

The following list outlines the general removal steps, though exact motion can vary slightly by connector style.

1. Locate the release tab: On the underside or side of the wiper blade where it attaches to the arm, find a small plastic tab or button.
2. Press or pull the tab: Use your finger (or a small flat tool if needed) to press in or pull up the tab to release the lock.
3. Slide the blade off: While holding the tab, slide the blade down or away from the arm’s connector channel until it disengages.
4. Carefully remove the blade: Once free, angle the old blade away from the windshield and set it aside.
5. Do not let the arm snap back: Keep holding the arm or rest it gently against the padded area until the new blade is ready.

If the blade feels stuck, double-check the direction in which it’s meant to slide out and ensure the release tab is fully depressed before applying additional force.

3. Attach the New Wiper Blade

Installing the new blade is usually the reverse of removal: align the connector, slide until it clicks, and verify a secure fit. Many aftermarket blades come with multiple adapters; be sure you’re using the one specified for Audi A4.

The following list describes the typical process for attaching a new wiper blade to a 2017 Audi A4 wiper arm.

1. Select the correct adapter: If your replacement blade includes multiple adapters, consult its instructions to choose the one labeled for Audi or for your arm style.
2. Align the connector: Position the new blade’s connector with the arm’s end so that it slides into the channel or locking slot.
3. Slide the blade into place: Push the blade up or along the arm until you hear or feel a distinct “click” indicating the lock has engaged.
4. Check the connection: Gently tug on the blade to ensure it does not move or pull free from the arm.
5. Lower the arm carefully: Remove the protective towel if you are confident in the fit, then lower the arm back onto the windshield slowly and evenly.

Repeat this procedure for the other front wiper, making sure each blade is fully locked to its arm before you move on to testing.

4. Return the Wipers from Service Position and Test Them

Once both blades are replaced, the final step is to bring the wipers out of service mode and confirm they operate smoothly without noise or interference.

The following list explains how to reset the wipers and perform a basic functional test.

1. Turn on the ignition: Power up the car’s electronics by pressing the start button (without starting the engine) or turning the key.
2. Activate the wipers: Move the wiper stalk to a low-speed or single-wipe position; the wipers should sweep down from service position and settle in their normal parked location.
3. Spray washer fluid: Use the windshield washer function to apply fluid and let the blades operate several passes.
4. Observe the sweep: Check that the blades clean the glass evenly without streaking, skipping, or hitting the A-pillars or hood.
5. Listen for noise: Note any squeaking or unusual chatter; if present, clean the glass or confirm the blades are seated correctly.

If the wipers park in the wrong spot or collide with bodywork, double-check installation and consult the owner’s manual for any model-specific calibration instructions.

Care and Maintenance After Replacement

Proper maintenance after installing new blades will extend their life and keep the 2017 Audi A4’s visibility as clear as possible throughout changing seasons.

Cleaning and Seasonal Tips

Even high-quality blades degrade faster if they operate over dirty glass, ice, or heavy debris. Regular light maintenance can preserve performance and prevent early replacement.

The following list outlines simple practices to maintain new wipers on a 2017 Audi A4.

• Clean the windshield regularly: Use glass cleaner and a microfiber cloth to remove road grime, film, and insect residue.
• Wipe the blade edges: Occasionally clean the rubber edge gently with a damp cloth to remove buildup.
• Avoid dry wiping: Do not run wipers on a completely dry windshield; use washer fluid first to lubricate the pass.
• Lift blades in heavy snow/ice: In winter conditions, consider lifting blades off the glass when parked to prevent them from freezing down.
• Defrost before use: Use the windshield defroster to melt ice before operating the wipers, so the rubber edge and motor are not overloaded.
• Inspect periodically: Check for damage after storms or car washes, and replace sooner if you notice cracks or deformation.

Summary

Replacing the windshield wipers on a 2017 Audi A4 involves putting the wipers into service position, lifting each arm, releasing the old blade via its connector tab, sliding on a correctly sized replacement, and then testing the system. Using OEM-spec beam blades in approximately 24-inch (driver) and 20-inch (passenger) sizes ensures proper fit and performance. With basic precautions—such as protecting the glass from the bare metal arm and confirming each blade clicks firmly into place—the job can be done safely at home in a few minutes, improving visibility and safety in adverse weather.
