Bosch 17124 left oxygen sensor for the 2007-2010 BMW X5 V8 4.8L measures the oxygen content of the exhaust so the engine computer can track the air-fuel ratio. This Bosch O2 sensor is a wideband type that reports the air-fuel ratio across the full lambda range.
A check engine light, a rough idle or poorer fuel economy can mean the sensor is worn, though a failing mass airflow sensor or a worn spark plug can be behind the same symptoms, so find the cause before you replace it.
This sensor is a direct-fit replacement for the 2007-2010 BMW X5 V8 4.8L, which takes one on the upstream left. The listing is a single sensor, and the right side is ordered separately.
