4x 433MHz TPMS Sensor For Mercedes

Each sensor measures approximately 5.2 cm in height and 3.8 cm in diameter, with a lightweight plastic housing weighing around 35 g per unit. Designed for precise tire pressure monitoring, these sensors operate at a stable 433 MHz frequency and are fully compatible with the original OE system without requiring reprogramming in most supported models. They feature a standard battery-powered design with typical operational life of 5–7 years depending on usage conditions. The set includes four identical new sensors, each sealed in individual protective packaging. These sensors directly replace part number A0009050030 and are engineered to integrate seamlessly with Mercedes-Benz’s factory TPMS warning system. They transmit real-time pressure and temperature data to the vehicle’s onboard display, helping prevent under-inflation related wear, improve fuel efficiency, and enhance safety during daily driving or longer journeys. Ideal for DIY replacement on common Mercedes models including W176, W246, W204, W205, C204, C117, X156, W166, W217, W222, W447, R231 and R172 — all built from mid-2011 onwards. No additional tools or coding required for basic installation; simply mount onto valve stems and reset via dashboard menu (procedure varies by model).
