Bosch 16116 Oxygen Sensor - Downstream Right

Bosch 16116 Oxygen Sensor for Mercedes-Benz

Bosch 16116 is an Actual OE Oxygen Sensor built as a standard replacement for precise air-fuel-ratio feedback to the ECU. It is a heated narrow-band sensor with a specific-fit design, made for stable combustion control and lower emissions in demanding operating conditions.

Compatible with 2010-2013 Mercedes-Benz S400, downstream right, this Bosch oxygen sensor supports accurate closed-loop operation where the engine management system depends on fast, reliable signal response. The Bosch 16116 is also referenced for Mercedes-Benz S400 downstream right applications where OE-style fit and sensor performance matter.

Product Details

Bosch developed its oxygen sensor technology from early thimble-style designs to later planar narrowband sensors that improve light-off speed, lambda accuracy, and closed-loop response. The Bosch 16116 uses advanced ceramic sensing elements, controlled heater operation, and heat-resistant materials to maintain consistent signal output under thermal cycling and vibration. For Mercedes-Benz S400 owners, this part number 16116 provides OE-proven sensor architecture for downstream right placement.

This part cross-references Mercedes-Benz OE number 0065424018 for the same application.

Common Issues This Sensor Can Address

• Faulty oxygen sensor signal causing incorrect fuel trim readings
• Check engine light related to downstream oxygen sensor performance
• Rough idle or unstable combustion control from aging sensor response
• Increased emissions from inaccurate exhaust oxygen measurement
• Delayed closed-loop operation after sensor wear or contamination

Installation Notes and Tips

Confirm the downstream right location before installation and verify connector shape, wire count, and thread size against the removed sensor. The threaded 18 mm design and 22 mm hex size support standard oxygen sensor service procedures. Inspect the harness routing and connector condition before connecting the Bosch 16116 to the vehicle harness.

Quality Assurance

Bosch backs this oxygen sensor with more than five decades of OE development in emission control sensing. The 16116 is built to Bosch OE standards for accurate signal delivery, thermal durability, and dependable operation in Mercedes-Benz S400 downstream right applications.
