大众奥迪 氧传感器 1K0998262AA 通用型替代0258007363/7364

If your vehicle shows idle instability, noticeably higher fuel consumption, stronger odor in exhaust, or the engine warning light (codes such as P0130, P0135) is on, the oxygen sensor may be aging or failed. This sensor monitors exhaust oxygen content in real time and feeds the signal to the ECU to precisely adjust the air–fuel ratio, ensuring efficient combustion and reduced emissions. This is a VW/Audi-specific oxygen sensor, OEM 1K0998262AA, compatible replacement for 0258007363/7364; fits VW Sag Teno, Passat, Jetta, and Audi A3, A4L, among others. Installation must be done with the car cold; disconnect the battery negative before replacing; ensure the sensor wiring is routed away from hot exhaust surfaces.
