Audi ambient sunlight sensor, part number 8V0907451B—a used OEM component removed from a donor vehicle. Also known as the sun light sensor, it measures cabin light levels for automatic headlight and interior lighting control. When this sensor fails, your headlights may stay on constantly, fail to auto-dim, or trigger a dashboard warning. Fits EA888 2.0 TSI/TFSI and other engine variants in A3, S3, and RS3 models. A genuine replacement ensures proper daytime running light and auto-headlight function.
