What Size Wiper Blades for Audi A6 C7?

The Audi A6 C7 typically uses a 24-inch wiper blade on the driver’s side and a 20-inch blade on the passenger side for most model years, with a 12–13-inch rear wiper on Avant (wagon) versions, depending on market and trim. Below is a detailed breakdown by model year, body style, and tips for choosing and fitting the correct blades.

Overview: Understanding Wiper Sizes on the Audi A6 C7

The Audi A6 C7 generation, produced roughly from 2011 to 2018 (pre- and post-facelift), uses a fairly consistent front wiper setup across most regions: a longer blade for the driver and a shorter one for the passenger. Avant (wagon) and allroad variants add a separate rear wiper, while standard sedans do not have a rear blade.

Front Wiper Blade Sizes by Model Year

This section explains how front wiper sizes are assigned across the Audi A6 C7 range and clarifies minor variations that may exist between markets and suppliers.

• Model years: Approximately 2011–2018 (C7 and C7.5 facelift)
• Typical front sizes (most markets):
  

  • Driver side: 24 in (600 mm)
  • Passenger side: 20 in (500 mm)

• Body styles using these sizes:
  

  • Saloon/Sedan (A6)
  • Avant (A6 Avant)
  • A6 allroad (based on Avant body)

• Engine/trim independence: Sizes are generally the same for petrol, diesel, TDI, TFSI, Quattro, S line and similar trims.
• Left-hand vs right-hand drive: Blade lengths usually remain 24″/20″, although sweep pattern and part numbers may differ slightly by region.

In practice, nearly all Audi A6 C7 owners will need a 24-inch driver and 20-inch passenger blade for the front windshield, regardless of engine or trim, making it relatively straightforward to purchase replacements.

Rear Wiper Blade Sizes for Avant and Allroad

While sedan versions of the Audi A6 C7 do not include a rear wiper, Avant and allroad variants are equipped with a smaller rear blade sized specifically for the tailgate glass.

• Applicable models:
  

  • Audi A6 C7 Avant (wagon/estate)
  • Audi A6 allroad (C7, based on Avant)

• Typical rear wiper size: 12–13 in (300–330 mm), depending on manufacturer specification.
• Common aftermarket listing: Often sold as 12″ (305 mm) for A6 Avant C7 in many markets.
• Mounting style: Dedicated rear arm fitting; ensure compatibility by checking the catalog, not just length.
• Sedan/Saloon models: No rear wiper blade fitted from the factory.

Because rear wiper fitment depends more on the arm design than merely the length, owners of A6 Avant and allroad models should confirm the recommended rear size (typically around 12″) using a parts catalog or VIN-based lookup when ordering.

OEM Part References and Compatibility

This section outlines original-equipment (OEM) style references and compatibility notes to help ensure that replacement wipers seat properly and clear the windshield effectively.

• Blade type:
  

  • Audi A6 C7 uses “flat” or “aero” style blades from the factory.
  • These are low-profile, beam-type blades designed for high-speed stability and even pressure.

• Front blade sets: Sold by Audi and major aftermarket brands as a matched 24″/20″ pair.
• Typical OEM-style supplier codes:
  

  • Bosch Aerotwin kit for Audi A6 C7 front (varies by region; codes differ between Europe, US and Asia).
  • Valeo, SWF and other OE suppliers also offer dedicated A6 C7 kits.

• Hook/adapter style: The A6 C7 generally uses specific push-button or side-pin style connectors rather than a classic “J-hook”; ensure adapter compatibility before purchase.
• Regional differences: Part numbers can differ between Europe, North America and other markets, but lengths remain 24″/20″ in most catalogs.

Although part numbers and connector styles vary between brands and markets, choosing a kit explicitly labeled for the Audi A6 C7 model years will nearly always provide the correct 24″/20″ lengths and the right mounting adapters.

How to Confirm the Correct Wiper Sizes for Your A6 C7

There can be minor differences in listing between brands and markets, so it is wise to double-check fitment before ordering new blades, especially if your car is a facelifted model or an Avant/allroad with a rear wiper.

1. Check your owner’s manual: Audi usually lists the official blade sizes and part references in the maintenance section.
2. Use VIN-based lookup: Many dealer and parts websites allow you to enter your Vehicle Identification Number to retrieve exact part specifications.
3. Measure existing blades: Use a tape measure to confirm the length of your current driver, passenger and (if applicable) rear blades.
4. Consult an online parts catalog: Filter by make, model, year and body style (e.g., A6 Avant vs A6 Sedan) to avoid confusion.
5. Verify connector type: Ensure your chosen wipers come with the correct adapter for the A6 C7’s arm design.

By cross-referencing the manual, VIN-based tools and the actual measurement on your car, you can be confident that a 24″/20″ front pair—plus a roughly 12″ rear blade on Avant models—will fit correctly and perform as intended.

Choosing Quality Replacement Blades

Beyond simply matching the length, the quality and design of the wiper blade have a direct impact on visibility, noise, and longevity, which is especially important on a premium vehicle like the Audi A6 C7.

• Beam vs conventional blades:
  

  • Beam (aero) blades, like the factory fitment, offer better wind resistance and more uniform pressure.
  • Conventional frame blades are cheaper but usually not recommended as a downgrade for this model.

• Rubber compound: Higher-grade rubber or silicone blends resist UV damage and streaking for longer.
• Winter-specific blades: In snow-belt regions, winter blades can resist icing, but must still match 24″/20″ sizing and proper connectors.
• Noise and chatter: Premium brands typically provide quieter operation, especially at motorway speeds.
• Service interval: Most manufacturers recommend changing wipers every 6–12 months, or sooner if you see streaks or hear squeaking.

Prioritizing OEM-equivalent or higher-quality beam blades in the correct 24″/20″ configuration for the front—and the correct smaller size for the rear—ensures that your Audi A6 C7 maintains clear visibility and operates as silently as the factory intended.

Installation Tips for the Audi A6 C7

Replacing wiper blades on the A6 C7 is generally straightforward, but the design of the arms and the proximity of the bonnet mean a few simple precautions can prevent damage.

1. Use “service position” if available: Many A6 C7 models allow you to move the wipers into a raised service position via the MMI or a stalk command with the ignition off.
2. Lift one arm at a time: Support the arm carefully to avoid it snapping back onto the glass without a blade attached.
3. Follow the adapter instructions: Each brand’s adapter system is slightly different; align the clip and listen for a positive “click.”
4. Test sweep after installation: Run the wipers with washer fluid to ensure full, streak-free coverage and that blades don’t collide or overrun the edge.
5. Check for clearance on the bonnet edge: Make sure the blades sit low enough when parked and do not catch the hood when opening or closing.

Taking a few extra minutes to use the service position, secure the arms and test the sweep helps protect your windshield and confirms that the new blades, in their correct sizes, are properly installed.

Summary

For the Audi A6 C7 generation (roughly 2011–2018), the standard front wiper blade sizes are 24 inches for the driver’s side and 20 inches for the passenger side across most trims and markets. Avant and allroad versions add a smaller rear wiper, typically around 12 inches, while sedans do not have a rear blade. Owners are best served by choosing high-quality beam-type replacements that match these lengths and the correct connector type, confirming fitment via the owner’s manual or VIN lookup, and installing them using the car’s service position to protect both the arms and the windshield.
