Product Information

620 mm wire length with OE connector and heated probe.

Upstream oxygen sensors are responsible for measuring exhaust gases as they exit the engine. This information is sent to the DME, allowing the engine management system to adjust fuel trim and maintain the proper air-fuel ratio.

Oxygen Sensor
The oxygen sensor plays a critical role in engine management, fuel efficiency, and emissions control. By monitoring oxygen content in the exhaust stream, the sensor helps optimize combustion performance under varying operating conditions.

Common failure symptoms:

  • Reduced fuel mileage
  • Failed emissions testing
  • Check engine light
  • Poor driveability

About Genuine BMW

Genuine BMW parts are the same components used during factory production. When you order a Genuine BMW part, you're receiving the exact item sourced by BMW dealerships — built to BMW’s precise engineering and quality standards.

While BMW engineers each part, many are manufactured by well-known OEMs (Original Equipment Manufacturers) such as Lemförder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, and Corteco. These parts may even arrive in their OEM-branded packaging, alongside a BMW logo.

Look for OE tags throughout our listings to identify direct from BMW components — helping you save without compromising quality. Visit our FAQ for more insight on OEM vs. OE terminology.
