Product Details

The Valeo Silencio VisioBlade line is a dedicated OE product family focused on integrated wiping and washing performance. On this application, the blade delivers washer fluid along the full wiping path instead of relying on a separate nozzle spray pattern. That design helps distribute fluid more evenly across the windshield and can reduce freezing effects associated with conventional nozzle systems. Part number 178508 is listed for front use on Mercedes-Benz SL and GLE models with Magic Vision, including SL450, SL550, SL63 AMG, SL65 AMG, SL400, GLE43 AMG, GLE63 AMG, GLE63 AMG S, GLE350, GLE400, GLE550e, GLE300d, and GLE450 AMG.

This part cross-references Valeo OE applications such as 572324 and VI508 for the same application.

What It Helps Address

• Streaking or uneven wiping on the front windshield
• Poor washer-fluid coverage across the blade sweep
• Cold-weather spray freezing near conventional washer nozzles
• Fitment issues on Magic Vision-equipped Mercedes-Benz vehicles
• Worn beam blade performance on SL and GLE front applications

Installation Notes

Verify that your vehicle uses the Magic Vision system and the AQB1 connection type before ordering. This is a specific-fit blade set, so confirm the model year and front application match your Mercedes-Benz SL or GLE. The one-click connection is designed for a quick installation, but the blade still requires the correct adapter configuration for the listed application.
