Used OEM Audi dash sun light sensor (part 4G0907539A) – a genuine component that measures sunlight intensity to help the automatic climate control system adjust cabin temperature. This sensor is commonly found across several Audi models with various gasoline and diesel engines. When it fails, the HVAC may not compensate for sun load, leading to uneven cabin comfort.
