What Size Are the Rear Windshield Wipers for the Audi Q5?

The rear windshield wiper size for most Audi Q5 models is approximately 12 inches (about 300 mm), but the exact size can vary slightly by model year and wiper brand, so it is always wise to confirm compatibility using your vehicle’s year and trim.

Understanding Rear Wiper Sizes on the Audi Q5

The Audi Q5, produced since 2008, has used a fairly consistent rear wiper length across generations, but there are minor differences depending on the model year, region, and whether it is a standard Q5, SQ5, or Sportback. Rear wipers are sold by length and mounting type, and most major manufacturers list compatibility by vehicle year and model, which is the most reliable way to verify the exact size.

Typical Rear Wiper Sizes by Audi Q5 Generation

While Audi does not usually market wiper dimensions prominently, aftermarket catalogs and fitment guides provide reasonably consistent size data by generation and model year. The sizes below reflect common fitments used by major wiper brands and dealer parts.

First Generation Audi Q5 (2009–2017, including early SQ5)

For the first-generation Audi Q5 sold in North America and most European markets, the rear wiper is typically a single small blade mounted on the tailgate glass. Owners often need this information when changing to aftermarket blades or ordering online.

The following list outlines typical rear wiper sizes for first-generation Q5 models by year.

• 2009–2012 Audi Q5: Rear wiper blade commonly listed as 12 inches (300 mm).
• 2013–2017 Audi Q5: Rear wiper blade also typically listed as 12 inches (300 mm), with the same general fitment as earlier years.
• 2014–2017 Audi SQ5 (first-generation performance variant): Rear wiper blade generally the same as the standard Q5: 12 inches (300 mm).

Across the first generation, most major wiper brands (Bosch, Valeo, Trico, Rain‑X, and others) specify a 12-inch rear blade, making it a safe reference size as long as the correct mounting adapter is used.

Second Generation Audi Q5 (2018–present, including SQ5 and Sportback)

The second-generation Audi Q5, introduced for the 2018 model year, brought new styling and updated hardware, but the rear wiper dimensions remained largely comparable to the outgoing model. The wiper arm design changed slightly, but the blade length stayed close to prior years.

The following list shows typical rear wiper sizes for the second-generation Q5 and its variants.

• 2018–2020 Audi Q5: Rear wiper blade generally specified as 12 inches (300 mm).
• 2021–present Audi Q5 (including facelift years): Most parts catalogs continue to specify 12 inches (300 mm) for the rear wiper.
• 2018–present Audi SQ5: Rear wiper blade listings match the standard Q5 at 12 inches (300 mm).
• 2021–present Audi Q5 Sportback: Despite the sloping rear glass, aftermarket fitment guides still typically specify a 12-inch (300 mm) rear blade.

Although the rear glass shape and styling differ somewhat, especially on the Sportback, the effective wiping area is designed around roughly the same blade length as the conventional Q5, which is why catalog listings remain uniform.

Why the Exact Size Can Vary Slightly

When shopping for rear wipers, drivers often notice that some brands list 12 inches while others list nearby metric lengths, or offer “vehicle-specific” part numbers without clearly stating the size. This is due to small differences between nominal and actual blade lengths and the way companies round their measurements.

Imperial vs. Metric and Brand Rounding

Rear wiper sizes for European vehicles like the Audi Q5 are typically designed in metric, then converted to inches for some markets. That leads to slight variations in how sizes are presented on packaging.

The points below explain how those differences usually appear in catalog listings.

• Most Audi Q5 rear blades are designed to be around 300 mm, which converts to about 11.8 inches.
• Some brands round this to 12 inches for simplicity in the U.S. and other imperial markets.
• Others will explicitly print 300 mm and either omit the inch equivalent or list 11.8 inches.
• Vehicle-specific “rear integrated” blades often focus on fitment (Q5 2018–onwards etc.) rather than a precise length measurement.

For practical purposes, if you see 300 mm or 12 inches listed as compatible with your Q5’s model year, they typically describe the same rear blade length and will function equivalently as long as the mounting system is correct.

How to Confirm the Correct Rear Wiper for Your Audi Q5

Because minor differences can exist across markets and production runs, confirming fitment with your exact model year and VIN is the most reliable approach, especially if you are buying online or from a non-dealer retailer.

Checking with Official and Aftermarket Sources

There are several straightforward ways to ensure you’re getting the correct rear wiper blade for your specific Q5, even though the nominal size is generally the same.

The following steps outline practical methods to verify the correct part.

1. Owner’s manual: Many Audi Q5 manuals include a section listing wiper blade sizes or at least referencing the correct part numbers.
2. Dealer or OEM parts catalog: Providing your VIN to an Audi dealer or using official online parts catalogs will return the exact OEM rear wiper part number for your car.
3. Online fitment tools: Major wiper brands’ websites usually have “find your vehicle” tools where you select make, model, and year; they then list the specific rear wiper product that fits.
4. Existing blade measurement: If the original blade is still fitted, you can remove it and measure the rubber/overall length; it should be near 300 mm / 12 inches.
5. Check the mounting style: The Q5 uses a specific rear arm interface; ensuring the replacement blade includes the right adapter is just as important as the nominal length.

By using one or more of these confirmation methods, you reduce the possibility of buying a blade that technically has the right length but does not clip properly onto the rear wiper arm of your specific Q5 variant.

Common Aftermarket Rear Wiper Options for the Audi Q5

Once you know that your Audi Q5 uses roughly a 12-inch (300 mm) rear wiper, you can choose from a wide range of aftermarket blades, including traditional rubber, beam-style, and model-specific integrated designs.

Popular Brands and Product Types

Many brands sell rear blades that explicitly list compatibility with Audi Q5 model years. The functional differences often come down to rubber quality, durability, and noise levels rather than size.

The following list summarizes common aftermarket choices that typically offer rear blades designed for the Audi Q5.

• Bosch: Widely used on European vehicles, Bosch offers rear-specific blades that are often direct-fit for the Q5’s OEM arm design.
• Valeo: Another major supplier for European brands, with rear wipers cataloged specifically for Audi models, including Q5 and SQ5.
• Trico: Provides rear blades matched by vehicle lookup tools, frequently listing 12-inch options for Q5 rear fitment.
• Rain‑X: Offers generic “rear” blades and some vehicle-specific kits; size is listed around 12 inches or 300 mm for Q5 compatibility.
• OEM Audi blade: Available via dealers or OEM-focused online stores, using the exact original design and mounting interface.

Whichever brand you select, checking that the packaging or online listing explicitly mentions your Q5 model year is the best assurance that both the blade length and mounting style will be correct.

Summary

For most Audi Q5 and SQ5 models, including both first-generation (2009–2017) and second-generation (2018–present) vehicles, the rear windshield wiper blade is typically around 12 inches (approximately 300 mm) in length. While the nominal size is broadly consistent, minor variations in how brands label the blade and in the arm mounting design mean it is sensible to confirm compatibility via your owner’s manual, VIN-based parts lookup, or a reputable wiper brand’s fitment guide. In practice, a 12-inch (300 mm) rear blade specified for your exact Q5 model year will be the correct choice for replacement.
