The Xenons4U Mercedes-Benz A0009053009 A2C15462900-02 SNS381B NOX Sensor is a direct replacement for faulty genuine Continental or Mercedes-Benz brand parts. If your car's check engine light is on and displays error codes like P229F62, P2202, U029E00, U029E, U029D00, or U029D, it indicates a failed NOX sensor. Timely repair is recommended to prevent damage to the DPF filter, as clogging can result in costly repairs. NOX stands for Nitrogen Oxide. The sensor information from the original part includes LUNOX-SENSOR, LU NOX-SENSOR, SNS 12V Gen3.0, NS0004, ZGS001, Q01, and SNS381B. After installing the new NOX sensor, error cleaning can be performed independently, without visiting a Mercedes-Benz dealer. The A0009053009 SNS381B sensor is compatible with various Mercedes-Benz cars.
