Used OEM Audi Idler Pulley / Relay Roller Dust Cap, part number 059903310B (also replaces 059903310). This genuine cap shields the idler pulley or relay roller from dirt and debris. A cracked or missing dust cap lets contaminants enter the bearing, accelerating wear and causing belt noise or tension loss. Fits Audi and VW models equipped with 2.9L, 3.0L, or 4.0L V6 and V8 engines (turbo, supercharged, diesel, hybrid).
