What Size Wiper Blades for Audi A5 2017?

The 2017 Audi A5 typically uses a 24-inch wiper blade on the driver’s side and a 20-inch blade on the passenger’s side for most coupé and Sportback models, while many Cabriolet (convertible) versions use a 24-inch driver’s side blade and a shorter 19-inch passenger’s side blade. Exact sizing can vary slightly by body style and market, so cross-checking with your vehicle manual or a fitment guide is recommended.

Understanding Wiper Blade Sizes for the 2017 Audi A5

The 2017 Audi A5 range includes multiple body styles—Coupé, Sportback, and Cabriolet—as well as different trim levels. While Audi tends to standardize wiper sizes across a generation, minor differences can appear between markets or specific variants. Knowing the correct size is crucial to ensure full windshield coverage, prevent wiper motor strain, and maintain safe visibility in bad weather.

Typical Wiper Blade Sizes by 2017 Audi A5 Variant

The following breakdown summarizes the most commonly specified front wiper blade sizes for the 2017 Audi A5 lineup. This reflects typical European and North American specifications from major parts catalogs and fitment tools. Drivers should still verify against their exact model, VIN, or owner’s manual to confirm compatibility.

• Audi A5 Coupé (2017, B9 generation): Driver: 24″ (600 mm), Passenger: 20″ (500 mm)
• Audi A5 Sportback (2017, B9 generation): Driver: 24″ (600 mm), Passenger: 20″ (500 mm)
• Audi A5 Cabriolet / Convertible (2017, B9 generation): Driver: 24″ (600 mm), Passenger: 19″–20″ (475–500 mm), with 19″ being common in many catalogs

These dimensions reflect the most widely listed fitments from major wiper manufacturers such as Bosch, Valeo, and others. Because some Cabriolet models and regional trims may show slight variations, confirming the passenger-side blade length before purchase helps avoid mismatch or incomplete wiping arcs.

How to Confirm the Correct Wiper Size for Your A5

Check the Owner’s Manual and Existing Blades

Audi provides the official blade sizes and specifications in the owner’s manual and service documentation. When in doubt, this is the most authoritative source for your particular vehicle configuration and market.

The steps below describe practical methods to confirm your wiper blade sizes directly on the car or using official references, which is especially useful if your vehicle has had windshield or arm replacements in the past.

1. Consult the owner’s manual: Look under the “Wiper blades” or “Maintenance” section for listed sizes or part numbers.
2. Measure your existing blades: Use a tape measure to check the length of both front wipers from end to end in inches or millimeters.
3. Check for OEM part numbers: If original Audi blades are still installed, note the part numbers printed on the rubber or plastic and cross-reference them with online catalogs.
4. Use an online fitment tool: Enter “Audi A5 2017” with your body style (Coupé, Sportback, Cabriolet) on a reputable parts site or manufacturer’s website (e.g., Bosch, Valeo, Rain-X) to confirm sizes.
5. Ask a dealer or specialist: Provide your VIN at an Audi dealer or trusted parts counter to obtain exact OEM specifications for your specific build and market.

Following these steps reduces the risk of buying blades that are slightly too long or short, which can result in poor wiping performance, chattering, or contact with the windshield frame and A-pillars.

Choosing the Right Type of Wiper Blade

Beyond length, the type and quality of the wiper blade can significantly affect visibility and durability. The 2017 Audi A5 commonly uses “beam” or “aero” style blades that match the car’s factory design and windscreen curvature.

• Beam (aero) blades: Recommended to match OEM style; offer even pressure distribution, low wind lift, and quieter operation at highway speeds.
• Premium rubber compounds: Look for graphite- or silicone-enhanced rubber for smoother wiping and better longevity, especially in harsh climates.
• Winter-specific blades: In heavy-snow regions, winter blades or all-weather premium blades resist ice buildup and remain flexible at low temperatures.
• Direct-fit adapters: Many aftermarket kits include specific adapters for Audi’s arm type; using the correct adapter ensures secure attachment and proper angle.

Selecting high-quality, beam-style blades in the correct size helps maintain the A5’s OEM-level performance, reduces noise and streaking, and can extend intervals between replacements.

Replacement Frequency and Maintenance Tips

Even the correct size wiper blade will underperform if it is worn or damaged. The 2017 Audi A5’s windshield angle and aerodynamics mean that degraded blades can quickly result in streaks, juddering, or missed patches in the driver’s line of sight.

• Typical replacement interval: Every 6–12 months, depending on climate, driving frequency, and exposure to sun, dust, or road salt.
• Visual inspection: Check for cracks, splits, or warped rubber edges and replace at the first sign of deterioration.
• Clean regularly: Wipe the rubber edge with a damp cloth and clean the windshield with glass cleaner to remove film and debris.
• Avoid dry-wiping: Don’t run wipers on a dry windshield; this accelerates wear and can cause chatter and scratching.
• Lift in winter storms: In icy conditions, lift wipers off the glass when parked (if safe to do so) to prevent freezing and tearing.

Applying these maintenance habits not only extends the life of your wiper blades but also preserves the clarity and safety of your forward view, particularly in rain, snow, and road spray.

Summary

For most 2017 Audi A5 Coupé and Sportback models, the standard wiper blade sizes are 24 inches for the driver’s side and 20 inches for the passenger’s side. Many 2017 A5 Cabriolet models pair a 24-inch driver’s blade with a slightly shorter 19-inch passenger’s blade, though some catalogs list 20 inches. Because slight variations can exist between trims and regions, the safest approach is to confirm sizes via the owner’s manual, direct measurement, or an official fitment guide. Correctly sized, high-quality beam-style blades, replaced regularly and maintained properly, will help keep your A5’s windshield clear and your driving visibility as sharp as Audi intended.
