Replacement blade options and brands
There are several reputable brands offering 12-inch rear wiper blades suitable for the 2018 Audi Q5. These brands typically provide blades with the correct mounting adapters for common Audi wiper arms.

When choosing, ensure the blade includes a compatible mounting adapter for your tailgate wiper arm, as some blades use specific adapters or require a universal adapter kit.
How to measure and install the blade
If you want a quick DIY guide for measurement and installation, follow these steps:
- Gently lift the wiper arm away from the glass until it stays in a safe, upright position.
- Release the old blade by using the locking tab or lever on the blade housing, then remove it from the arm.
- Measure the new blade or check the packaging to confirm a 12-inch (304 mm) length.
- Attach the new blade to the wiper arm using the included adapter, ensuring a secure fit.
- Lower the arm back onto the glass and test the wipe with a light spray of water to confirm proper contact and clearance.
A properly installed blade should wipe cleanly without streaks and operate with minimal noise. Replace the blade every 12–24 months or sooner if you notice streaking, skipping, or performance decline.
