When your BMW E87/E88/E90/E91 shows check engine light, unusually high fuel consumption, rough idle, or noticeable exhaust odor, this typically indicates the downstream oxygen sensor has aged or failed and cannot accurately monitor exhaust oxygen. In normal operation, this sensor provides real-time data to the ECU to precisely adjust the air-fuel ratio for efficient engine operation and reduced emissions. This product is an OEM-spec downstream oxygen sensor, OEM number 11787545074, compatible with model 0258006795, fitting BMW 1 Series (E87/E88) and 3 Series (E90/E91) and other models. During installation, ensure cold engine operation, avoid scalding; disconnect the battery negative before disassembly and ensure the sensor connector is clean and oil-free. Tightening torque should follow the repair manual strictly.
