Original VAG interior trim component. Equipped with an electronic system featuring integrated light intensity sensors (front and rear sensors), which automatically and smoothly dims the glass when it detects the lights of a vehicle approaching from behind, preventing the driver from being dazzled while driving at night.

Fitment guarantee and VIN verification

Every mirror undergoes a photocell response test to a light source and a ball joint stability check before shipping.

Fitment / installation tip: The base designation 8W0 857 511 B (mirror group 857) is the standardized frameless mirror for the new generation of MLBevo platform vehicles. To install the mirror, slide the metal base onto the bracket glued to the windshield and lock it by rotating it 45–90 degrees (caution should be exercised to avoid damaging the front windshield). The component also often controls the dimming signal for the exterior rearview mirrors (if the car has photochromic exterior mirrors). Before purchasing, we recommend comparing the OE number on the base or verifying fitment using the vehicle's VIN.
