Açıklama
This Mercedes-Benz air quality sensor is a genuine OEM electronic component for the Mercedes W220 S-Class and W215 CL-Class. Primary OEM number 2208300172. It is designed to detect harmful gases in the incoming outside air, such as exhaust fumes, and to report the measured values to the climate control system of the vehicle.
Its job is to measure the pollution level of the air before it enters the cabin and send a signal to the climate control unit, which then closes the fresh air flap and switches to recirculation mode when the air is polluted. A properly working air quality sensor supports clean and healthy cabin air, a comfortable interior climate, and correct operation of the automatic climate control system.
Common signs of a faulty unit include the climate control staying in recirculation mode without reason, the fresh air flap that does not open or close at the right time, exhaust or other odors entering the cabin in heavy traffic, fogging of the windows caused by constant recirculation, and fault codes stored in the climate control system memory. When the sensor reports wrong values, the cabin air quality and the comfort of the passengers can suffer.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 2208300172 before ordering. Professional installation is recommended, and a diagnostic check of the climate control system may be needed where applicable, so confirm the fitment details and equipment version of your vehicle before you buy.
