Over time, this sensor can become worn, damaged, or non-functioning, resulting in erratic climate control responses or insufficient light adjustments. Alternate names include Sunlight Sensor and Ambient Light Sensor. Compatible models include the Audi A3 (2005-2011) and A4 (1996-2011), as well as Audi S4 and RS4 from select years.
