What Windshield Wipers Do I Need for My Audi A4?

You need wiper blades that match the exact model year and body style of your Audi A4, with most modern A4s (roughly 2009–present) using approximately a 24″ driver-side blade and a 20″ passenger-side blade, plus a specific rear blade size for Avant and Allroad wagons; the safest choice is to use a fitment tool from a major brand (Bosch, Valeo, Michelin, Trico, or Audi OEM) and select blades listed as compatible with your specific year, trim, and whether your car is a sedan, Avant, Allroad, or Cabriolet.

Why Wiper Size and Type Matter on an Audi A4

Choosing the right windshield wipers for an Audi A4 is less about guesswork and more about matching size, mounting style, and climate. The A4 uses model-specific fittings that differ between generations (B6, B7, B8, B9) and between sedans, wagons, and convertibles. Using the wrong length can reduce visibility, cause chattering, or even lead to blades striking the windshield frame.

Typical Wiper Blade Sizes by Audi A4 Generation

The following overview summarizes the most common front and rear wiper sizes for the Audi A4 sold in North America and most European markets. Always double-check with a parts catalog or your owner’s manual, because mid-cycle changes and regional variations can occur.

Audi A4 B6 (2001–2005) and B7 (2005–2008)

These older generations often use traditional frame-style or early “aero” flat blades, depending on market and exact trim. Sizes below reflect common fitments.

• B6/B7 Sedan & Avant (2001–2008)
  

  • Driver side: typically 22″ (560 mm)
  • Passenger side: typically 20″ (500 mm)
  • Rear (Avant): typically 15″ (380 mm)

• B6/B7 Cabriolet (Convertible)
  

  • Front blades are often slightly shorter than sedan/Avant equivalents, frequently around 21″ driver and 19–20″ passenger
  • No rear wiper

Because B6/B7 production spans many years and multiple markets, there are more variations here than on newer cars. A VIN-based lookup at a dealer or trusted parts site is strongly recommended for these models.

Audi A4 B8 (2009–2016)

From the B8 generation onward, Audi standardized more on flat “beam” blades and specific arm mounts, making fitment more consistent across trims and markets.

• B8 Sedan (2009–2016)
  

  • Driver side: about 24″ (600 mm)
  • Passenger side: about 20″ (500 mm)
  • No rear wiper

• B8 Avant (Wagon, not sold in all markets) and B8 Allroad
  

  • Front: same as Sedan — 24″ driver, 20″ passenger
  • Rear: typically 13″–14″ (330–350 mm), depending on exact year

The B8 generation is well-supported by major aftermarket brands, so using an online “vehicle selector” by year/model usually returns the correct beam-type blades very reliably.

Audi A4 B9 (2017–Present)

The current B9 A4 and its facelift versions (often grouped as B9.5 around 2020+) largely maintain the beam-blade layout and similar sizes, but with refined mounting hardware.

• B9 Sedan (2017–present)
  

  • Driver side: about 24″ (600 mm)
  • Passenger side: about 20″ (500 mm)
  • No rear wiper

• B9 Avant and B9 Allroad (markets where available)
  

  • Front: again, typically 24″ driver, 20″ passenger
  • Rear: usually around 13″ (330 mm), but check catalog by year

For B9 models in particular, blades listed as “direct-fit beam” or “vehicle-specific beam” from major manufacturers will usually clip on without adapter pieces and match the factory wiping pattern closely.

How to Identify the Correct Wipers for Your Specific Audi A4

Although size charts are helpful, the most precise way to find the correct blades is to use tools and references that match the exact year, body style, and sometimes trim of your A4.

Use an Online Fitment Tool

Several major parts retailers and wiper manufacturers offer databases that are updated regularly. These are generally the most reliable sources for up-to-date fitment, including regional differences.

The following list highlights common ways you can quickly confirm the correct wiper blades online or through official channels.

1. Manufacturer websites: Bosch, Valeo, Trico, Michelin, and Rain-X have “Find your wiper” tools where you enter make, model, and year.
2. Parts retailers: Sites like RockAuto, AutoZone, Advance Auto Parts, O’Reilly, Halfords (UK), and others provide vehicle selectors with current catalog data.
3. Audi dealer parts catalog: An Audi parts department can look up the exact OEM part numbers by VIN, which is especially useful for older B6/B7 or very new model years.
4. Owner’s manual: Many A4 manuals list wiper blade sizes and Audi part numbers in the maintenance or technical data section.

Using more than one of these sources—for example, an online tool plus your owner’s manual—helps confirm that you’re ordering the correct blades and not relying on a single database entry that could be outdated or incomplete.

Check the Mounting Style

Beyond length, wipers must match the arm mount. Audi A4 models, especially newer generations, often use specific low-profile mounts that differ from standard J-hook arms found on many older cars.

The following key mounting considerations will help you avoid blades that technically “fit” in length but won’t attach properly or sit correctly on the glass.

• Beam vs. conventional: Most B8 and B9 A4s use beam (flat) blades with integrated spoilers, not conventional metal-frame wipers.
• Connector type: A4s may use side-pin, top-lock, or a proprietary “aero” connector. The blade packaging should explicitly list “Audi A4 (year)” compatibility.
• Vehicle-specific kits: Some brands sell A4-specific sets (driver + passenger, or full front + rear kits), which simplify installation and connector compatibility.

Confirming the connector type is as important as confirming length; a correct-length blade with the wrong connector generally will not install securely and could fail during use.

OEM vs. Aftermarket: Which Wiper Blades Are Best for an Audi A4?

Audi owners can choose between genuine OEM blades and high-quality aftermarket options. Each approach has pros and cons in terms of cost, longevity, and performance in specific climates.

Genuine Audi (OEM) Wiper Blades

OEM blades, sold through Audi dealers or authorized parts outlets, are engineered specifically for A4 arm geometry and windshield curvature.

The following points summarize the main advantages and trade-offs of sticking with OEM wipers on your A4.

• Perfect fitment: Designed for your exact arm type and windshield contour, giving smooth, quiet operation.
• Consistent quality: Rubber compound and tension matched to the vehicle, which can be especially noticeable at highway speeds.
• Higher price: Typically more expensive than aftermarket options with similar performance.
• Dealer availability: Easy to source at Audi dealers, but may require a visit or shipping wait.

For drivers who value “factory-original” performance and minimal hassle, OEM blades are a reliable—but sometimes costly—choice.

Aftermarket Premium Beam Blades

Many Audi A4 owners opt for premium aftermarket blades that meet or exceed OEM specifications while offering broader availability and sometimes better pricing.

The following popular aftermarket choices are widely available for Audi A4 models and are known for solid performance and compatibility.

• BOSCH Aerotwin / ICON (Clear Advantage in some markets)
  

  • Often considered the closest to or better than OEM in performance.
  • Direct-fit kits for many A4 model years, including B8 and B9.

• Valeo Silencio / Ultimate / HydroConnect
  

  • Common on European vehicles; excellent compatibility with Audi mounts.
  • Quiet operation and good longevity.

• Trico Exact Fit / Beam line
  

  • Vehicle-specific connectors that tend to install without adapters.
  • Widely stocked by major U.S. retailers.

• Michelin Stealth / Endurance beam blades
  

  • Durable construction with strong performance in mixed weather.
  • Multiple adapter options—verify Audi compatibility before purchase.

• Rain-X Latitude / Silicone Endura
  

  • Known for water-repellent coating, helpful in heavy rain.
  • Check that the connector variant explicitly lists your Audi A4 model year.

When choosing aftermarket blades, prioritizing “vehicle-specific” or “direct-fit” Audi A4 kits minimizes installation issues and helps maintain the OEM wiping pattern and noise level.

Climate and Driving Conditions: Matching Blades to Real-World Use

Beyond fitment, your local climate should influence which wiper material and design you select for an Audi A4, especially in regions with harsh winters or strong sun.

For Snow and Ice

Drivers in cold climates benefit from blades that resist ice build-up and remain flexible at low temperatures.

The following characteristics are important if your Audi A4 frequently sees snow, slush, and road salt.

• Winter-specific blades: Some brands offer winter variants with protective rubber boots over the frame to prevent ice buildup (more common for older A4s with frame arms).
• Cold-rated rubber compounds: Beam blades advertised for winter use stay flexible and maintain contact with the glass in freezing conditions.
• Regular cleaning: De-icing the windshield and gently freeing stuck blades before driving reduces strain on the wiper motor.

For B8 and B9 models that already use beam blades, a winter-rated beam design is often sufficient, paired with thoughtful de-icing habits on very cold mornings.

For Hot, Sunny Climates

In high-UV environments, the primary concern is rubber degradation, which leads to streaking and noise.

Key considerations in warm regions help you maintain clear, streak-free vision year-round.

• Silicone or advanced rubber blades: Some premium models use silicone or UV-resistant compounds that resist cracking longer than standard rubber.
• Frequent replacement: Even premium blades may need replacement every 6–12 months in intense sun.
• Windshield care: Keeping the glass clean and free of residue reduces blade wear and chatter.

In hot climates, it can be more economical to use mid-range blades replaced regularly than expensive blades pushed far past their effective life.

How Often Should You Replace Wipers on an Audi A4?

Most experts recommend replacing wiper blades every 6–12 months, depending on climate and usage. Luxury cars like the Audi A4 benefit from fresh blades to match their high-speed stability and visibility standards.

The following signs indicate your wipers are due for replacement, regardless of calendar age.

• Streaking or smearing: Persistent streaks, especially in the driver’s line of sight, suggest hardened or damaged rubber.
• Chattering or skipping: Blades that bounce or chatter can indicate uneven pressure, warped frames, or dried-out rubber.
• Visible cracks or tears: Any obvious rubber damage means it’s time for a new set.
• Uneven wipe pattern: Missed zones or “rainbow” arcs show poor contact with the windshield.

Addressing these symptoms promptly not only improves visibility but also helps protect your windshield from scratching due to embedded dirt or hardened rubber edges.

Practical Step-by-Step: Confirming and Buying the Right Wipers

For an owner who just wants to get the correct blades with minimal confusion, a simple, structured approach works best.

The steps below outline a straightforward way to end up with correctly sized, properly fitting wipers for any Audi A4 generation.

1. Identify your exact car: Note the model year, body type (Sedan, Avant, Allroad, Cabriolet), and if possible, the generation (B6, B7, B8, B9). Your registration or VIN plate can help.
2. Check your owner’s manual: Look for the wiper section; note front and rear sizes if listed.
3. Use an online fitment tool: Go to a major brand’s website (Bosch, Valeo, Trico, Michelin, Rain-X) or a big retailer and enter your car details.
4. Confirm connector type: Ensure the blades are advertised as direct-fit or vehicle-specific for your Audi A4.
5. Choose OEM or a reputable aftermarket kit: Decide based on budget and availability; favor beam-style, premium options for B8/B9.
6. Buy as a set: When possible, purchase a driver/passenger pair, and a rear blade for Avant/Allroad models.
7. Install and test: Fit the blades according to instructions, then test with washer fluid to check for full coverage and quiet operation.

Following this process takes a few minutes but dramatically reduces the odds of buying the wrong size or connector and having to return parts or live with poor performance.

Summary

For most modern Audi A4 models (B8 and B9 sedans, Avants, and Allroads), you will typically need a 24″ driver-side and a 20″ passenger-side beam-style wiper blade, plus a roughly 13″–14″ rear blade on Avant and Allroad wagons. Older B6/B7 cars may use slightly shorter front blades and different rear sizes. Because of generational and regional differences, the best approach is to use your owner’s manual and a trusted online fitment tool—or an Audi dealer’s parts catalog—to select OEM or high-quality aftermarket blades labeled as direct-fit for your specific year and body style. Matching the correct size, connector type, and climate-appropriate rubber compound will ensure quiet, streak-free performance and maintain the visibility that an Audi A4 is engineered to deliver.

Do Audis need special wiper blades?

Modern Audis might favor beam blades for their arc matching the windshield’s curvature, whereas older models may still employ conventional blades. In any case, your choice should bolster the clear vision and premium feel synonymous with owning an Audi.

How do I tell what size wipers I need?

To find the right windshield wiper size for your car, check your owner’s manual, use an online wiper blade size finder, or ask an auto parts store for help using the year, make, and model of your vehicle. You can also measure the current wiper blades, but remember that many vehicles require different lengths for the driver’s side and passenger’s side.
 
Methods to find the correct size

• Check your owner’s manual: This is the most direct way to find the manufacturer’s recommended size, which is specific to your car’s make, model, and year. 
• Use an online tool: Many auto parts websites have a “wiper blade size finder” where you can input your vehicle’s information to get the correct sizes. 
• Visit an auto parts store: Employees at auto parts stores can look up the correct size for you, or you can use their in-store lookup charts. 
• Measure the existing blades: Measure the length of the current blades from end to end. It’s crucial to measure both the driver’s side and passenger’s side, as they are often different sizes. 

Important considerations

• Don’t guess: Using the wrong size can lead to poor cleaning or damage to your windshield and wiper arms. 
• Remember the rear wiper: If your vehicle has a rear wiper, you will need to find the correct size for that blade as well. 
• Match the arm attachment: Besides size, make sure the new wiper blade is compatible with the attachment type on your car’s wiper arm (e.g., hook, pinch tab). 

What wiper blades does Audi use?

Audi uses different wiper blade sizes and types depending on the specific model and year, so there is no single answer. For example, a 2019–2025 Audi sedan typically uses a 24-inch driver-side blade and a 20-inch passenger-side blade, while an Audi Q7 from 2023 uses 26-inch to 28-inch driver-side blades and a 15-inch rear blade. To find the correct size, it’s best to check your car’s owner’s manual or use an online vehicle lookup tool with your car’s specific details. 
Example wiper blade sizes for common Audi models
