Product Details

The Silencio VisioBlade line focuses on OE-level windshield cleaning performance with a fluid-in-blade design rather than a conventional nozzle-only approach. By distributing washer fluid through the blade itself, the system helps deliver more even coverage across the glass and can reduce freezing effects associated with exposed spray points. The Valeo 178505 is part of the Valeo OE family and is engineered for specific Mercedes-Benz fitment, including heated front windshield applications on the S-Class platform.

This part cross-references URO 2178202000 for the same application. If you are replacing a worn Mercedes-Benz windshield wiper blade set on an S560, S63 AMG, S65 AMG, or S550, the 178505 offers a direct OE-style service part with the correct connection style and blade lengths for the listed vehicles.

What It Helps Address

• Streaking caused by worn or hardened wiper rubber
• Uneven washer-fluid coverage on the windshield
• Poor winter wiping performance in freezing conditions
• Fitment issues from using the wrong connection type
• Reduced cleaning performance on heated front windshield systems

Installation Notes

Verify the vehicle’s front wiper configuration before ordering. This part is specific fit and uses the AQB1 connection type, so the correct adapters must be used for installation. Confirm the listed Mercedes-Benz model, year, and heated front application before replacing the existing blade set. For best results, install on a clean windshield and inspect the wiper arm condition at the same time.
