What Size Windshield Wipers for a 2012 Audi A5 Quattro?

The 2012 Audi A5 Quattro typically uses a 24-inch wiper blade on the driver’s side and a 20-inch blade on the passenger’s side; the rear wiper (if equipped, such as on Sportback models in some markets) is usually around 11–12 inches, but should be confirmed by VIN or trim. Below is a detailed breakdown of fitment, variations, and how to choose the right replacement blades.

Standard Wiper Blade Sizes for the 2012 Audi A5 Quattro

For most 2012 Audi A5 Quattro coupes and convertibles sold in North America and Europe, the front windshield wiper sizes are consistent across trims. The driver’s side is longer to maximize coverage in the primary field of vision, while the passenger’s side is shorter to avoid interference.

Front Wiper Blade Dimensions

The front wiper blades on the 2012 A5 Quattro are asymmetrical, meaning each side has a different length. This is intentional and helps follow the curved shape of the windshield while maintaining maximum visibility and safe clearing patterns.

• Driver’s side (left): 24 inches (approximately 600 mm)
• Passenger’s side (right): 20 inches (approximately 500 mm)
• Wiper type: Flat “beam” or “aero” style blades are standard-equipment style for Audi

These dimensions are used by major brands (Bosch, Valeo, Trico, Michelin, Rain-X, and OEM Audi) as the standard catalog fitment for the 2012 A5 Quattro, and using these lengths will maintain the intended wipe pattern without clashing or leaving excessive unwiped areas.

Rear Wiper (If Equipped)

Not every 2012 A5 Quattro has a rear wiper—coupes and Cabriolets generally do not. Some Sportback or hatch-style variants in certain markets do. When present, the rear wiper is much shorter and attaches differently from the front blades.

• Typical rear blade length: 11–12 inches (around 280–300 mm)
• Mounting: Dedicated rear wiper arm with a specific clip/lock style
• Variation: Size and connector style can differ by market and body style, so catalog lookup by VIN is recommended

Because rear wipers on Audi models can vary more than the front sizes, it is safest to check your vehicle identification number (VIN) or consult an online parts catalog for your exact body style and region if you have a rear wiper.

How to Confirm the Correct Size for Your Specific A5 Quattro

While 24-inch and 20-inch blades are the standard front sizes, small variations can exist between regions, body styles, and aftermarket catalogs. Verifying fitment before purchase helps avoid the problems caused by slightly too-long or too-short blades.

Ways to Double‑Check Fitment

There are several practical methods owners can use to verify wiper blade size before buying replacements, whether shopping online or at a parts store.

1. Check the owner’s manual: Audi typically lists the wiper blade sizes and service guidelines in the “Maintenance” or “Technical data” section.
2. Look up the car by VIN: Online OEM parts catalogs or dealer systems can match blade size and connector type to your exact car using the VIN.
3. Use major brand fitment tools: Bosch, Valeo, Rain-X, and others have year/make/model lookup tools that list the correct lengths and compatible product lines.
4. Measure the existing blades: If you still have the factory-type blades, measuring them with a tape measure in inches or millimeters can confirm length.
5. Ask the dealer or a trusted shop: Audi service departments can quickly supply the OEM part number and corresponding length.

Combining at least two of these checks—such as using a brand’s online catalog and verifying against your owner’s manual—offers the highest confidence that you’re buying the correct size and style for your specific A5 Quattro.

Choosing the Right Type of Wiper Blade

Beyond length, wiper blade design affects fit, performance, and noise. The 2012 Audi A5 Quattro was originally equipped with low-profile beam (aero) blades that match the contours of the windshield and arm design.

Blade Styles Compatible with the 2012 A5 Quattro

Owners can choose among several blade technologies as long as the sizes and mounting adapters match the Audi wiper arms. Different types offer trade-offs in performance, durability, and cost.

• Beam (aero) blades: These are the closest to OEM; they use a curved, frameless design that maintains even pressure and works well at higher speeds and in winter conditions.
• Hybrid blades: Combine aspects of conventional frames with an aero-style cover, offering improved aerodynamics and durability over older framed blades.
• Conventional frame blades: Typically cheaper and increasingly rare on modern European cars; not ideal for matching the A5’s original design and may not sit as cleanly on the glass.
• Winter blades: Designed with rubber boots and heavier construction to resist ice buildup, useful in harsh winter climates when combined with the correct lengths.

For most Audi A5 Quattro drivers, beam-style blades in the 24-inch (driver) and 20-inch (passenger) sizes provide the best balance of OEM-style fit, quiet operation, and good performance in both rain and snow.

Connector Types and Installation Considerations

Unlike many older cars that simply use a standard hook-style arm, the 2012 A5 Quattro can use more specialized connectors. Getting the correct adapter is as important as getting the correct length.

Understanding the Mounting System

The specific connector can differ slightly between regions and arm suppliers, but premium wiper brands usually provide adapters for European vehicles like the A5.

• Common connectors: Side-lock, top-lock, or pinch-tab style connectors that clip directly to the aero arm.
• Adapter kits: Many aftermarket blades (especially beam types) include multiple adapters in the package; you select and install the one that matches your Audi arm.
• OEM vs. aftermarket fit: OEM Audi blades will be a direct, tool-free replacement; aftermarket options may require one extra step to secure the correct adapter.
• Installation tip: Always protect the glass by laying a towel on the windshield before lifting the arm off the glass, in case it snaps back.

Taking a moment to confirm that the blade’s connector and adapter match your existing arm will ensure a secure fit and prevent chatter, streaking, or accidental detachment in use.

Maintenance and Replacement Intervals

Properly sized blades only work well if the rubber is in good condition. On performance-oriented cars like the A5 Quattro, clear vision is especially important, given the car’s higher-speed capabilities and frequent highway use.

How Often to Replace Wiper Blades

Environmental exposure, climate, and driving habits determine how long wiper blades last. Keeping an eye on wear patterns and performance can help you replace them before they become a safety issue.

• Typical interval: Every 6–12 months, depending on climate and exposure to sun, dirt, and road salt.
• Warning signs: Streaking, smearing, chattering, missed spots, or visible cracks and splits in the rubber edge.
• Seasonal checks: Inspect blades before winter and at the start of the rainy season to ensure reliable performance.
• Glass care: Regularly cleaning the windshield and wiper edges with glass cleaner or mild soap helps prolong blade life.

Routine inspection and timely replacement of your 24-inch and 20-inch blades (and rear blade, if applicable) will ensure your A5 Quattro maintains clear visibility in all weather conditions and preserves the windshield from abrasion.

Summary

The 2012 Audi A5 Quattro generally uses a 24-inch wiper blade on the driver’s side and a 20-inch blade on the passenger’s side, with an approximately 11–12-inch rear blade on models equipped with a rear wiper. These sizes match major OEM and aftermarket catalog listings and are intended to maintain the correct wipe pattern and visibility. Owners should confirm any rear wiper size and connector type by VIN or body style, select beam-style blades for OEM-like performance, and replace the blades every 6–12 months or at the first sign of streaking, noise, or reduced clearing efficiency.
