Bosch Actual OE Oxygen Sensor for BMW X5
Bosch Part Number 15335 is a specific-fit, narrow-band heated oxygen sensor for 2004-2006 BMW X5 applications. It is built to deliver accurate air-fuel-ratio feedback to the ECU for stable closed-loop control and emissions monitoring.
As part of Bosch’s Actual OE Oxygen Sensor line, this sensor reflects Bosch’s long OE development history in switching-type O2 sensor technology. The design uses advanced ceramic sensing elements, controlled heater operation, and high-temperature-resistant materials for consistent signal response in demanding exhaust conditions.
- Specific-fit oxygen sensor for BMW X5 downstream applications
- Fits 2004-2006 BMW X5, Downstream Left
- Fits 2004-2006 BMW X5, Downstream, Cylinder(s) 5 to 8
- Narrow-band heated sensor for closed-loop fuel control
- 4-wire design with round connector and blade terminals
- Threaded mounting with 18 mm thread diameter and 22 mm hex size
- Wiring harness included; harness length 42.2 in
- Metal housing for high-temperature exhaust service
How Bosch 15335 Works
Bosch 15335 monitors oxygen content in the exhaust stream and sends a switching signal to the engine control unit so the fuel mixture can be adjusted accurately. For BMW X5 models with downstream sensor placement, this helps the ECU verify catalyst performance and maintain proper emissions control. This part cross-references Bosch OE-style replacement applications for the same vehicle fitment.
Common Issues This Sensor Can Address
- Check engine light related to downstream oxygen sensor faults
- Slow or unstable oxygen sensor response
- Incorrect air-fuel ratio feedback to the ECU
- Emissions test failures tied to sensor performance
- Rough closed-loop fuel control after sensor degradation
Installation Notes
Confirm the downstream left or downstream cylinder 5 to 8 location before ordering Bosch Part Number 15335. The sensor uses an 18 mm thread and a threaded mount, so the exhaust bung and connector style should be checked against the original unit. Inspect the harness routing and connector orientation during installation to avoid strain or heat damage.
Quality Assurance
Bosch supplies OE-developed oxygen sensor technology to the aftermarket, using the same engineering approach that supports vehicle manufacturers. Bosch 15335 is built as a standard replacement part for direct-fit service on the listed BMW X5 applications.
