The rear wiper blade size for the 2012 Audi A3 is usually 11 inches (about 28 cm).
On the 8P generation A3, the rear window is relatively compact, and the blade is selected to provide full coverage without overhang. Variations can occur by market or body style, so it’s worth verifying the exact size for your specific car before purchasing replacements.
Confirming the correct size for your vehicle
To avoid buying the wrong blade, use the standard 11-inch size as a starting point, and confirm by measuring the existing blade or checking the owner’s manual or OEM parts catalog. If you’re unsure, bring the old blade to a parts retailer or dealer to match the length precisely.
- Most 2012 Audi A3 models with a rear wiper use a single 11-inch blade (280 mm).
- Regional or model-year variations are possible, so always verify with the exact vehicle specification.
- When in doubt, opt for an 11-inch replacement blade or consult the OEM part number for your market.
In short, plan on an 11-inch rear blade for the 2012 A3, but verify against your specific configuration to ensure a perfect fit.
Choosing your replacement: OEM vs aftermarket
When shopping, you’ll find both OEM-approved blades and aftermarket options. The key is the length—11 inches—so filter choices by blade length first, then compare mounting style and connection type to match your wiper arm.
OEM catalogs and reputable aftermarket brands commonly offer 11-inch rear blades for the 2012 A3. If you’re replacing a blade that has worn unevenly or caused streaking, selecting the correct size and a quality blade will help maintain clear rear visibility in adverse weather.
How to measure and replace
Follow these steps to confirm size and complete a safe replacement procedure:
- Park the car on a level surface and turn off the ignition.
- Open the rear hatch or tailgate to access the rear wiper arm.
- Raise the wiper arm away from the glass to expose the blade and its connector.
- Detach the old blade from its connector. Note how it is attached so you can replicate the setup with the new blade.
- Measure the total length of the old blade. If it measures around 11 inches (280 mm), you’ve got the standard size.
- Install the new blade by attaching it to the connector and lowering the wiper arm back onto the glass. Ensure the blade moves freely without contact with the car body.
- Test the rear wiper by turning it on to confirm full sweep and proper clearing of the glass.
Following these steps helps ensure you select the correct blade length and install it correctly for reliable rear visibility.
Summary
The standard rear wiper blade size for the 2012 Audi A3 is 11 inches. Always verify the size for your specific model and market, and consider OEM part numbers or trusted aftermarket options to ensure a proper fit and optimal performance.
