Bosch 16136 Oxygen Sensor - Downstream, Downstream Left or Downstream Right

Bosch OE Oxygen Sensor for Audi, Volkswagen, and Porsche

Bosch 16136 is an Actual OE Oxygen Sensor built for precise air-fuel-ratio feedback to the ECU. It supports stable combustion control and emissions monitoring on select Audi, Volkswagen, and Porsche applications, including downstream positions on the CC, Jetta, Passat, Touareg, A3 Quattro, and more.

• Actual OE Oxygen Sensor from Bosch
• Narrow-band heated oxygen sensor for downstream use
• Specific fit replacement with 4-wire harness included
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Oblong male connector with blade terminals
• Steel-finish metal housing for high-temperature service
• Wiring harness length: 26.6 in; overall length: 29.9 in

OE Sensor Line Details

Bosch’s Actual OE Oxygen Sensor line builds on the company’s long history in oxygen-sensing technology, including early thimble-style designs and later planar narrowband sensors. The result is a replacement sensor focused on fast light-off, accurate lambda feedback, and quicker closed-loop operation under changing exhaust temperatures and vibration.

Part number 16136 is a direct-fit narrow-band heated O2 sensor for downstream locations on select vehicles. It is used on applications such as Fits 2009-2017 Volkswagen CC, Downstream Right; Fits 2011-2015 Volkswagen Jetta, Downstream; and Fits 2007-2011 Audi A6 Quattro, Downstream. This part cross-references Bosch OE-style replacement numbers (e.g., 1K0998262S, 07L906265F) for the same application.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect downstream exhaust feedback to the ECU
• Slow sensor response during closed-loop operation
• Emissions test failures tied to aging O2 sensor output
• Rough combustion control caused by degraded air-fuel measurement

Installation Notes

Verify connector shape, wire count, and mounting position before installation. Bosch 16136 is a specific-fit, threaded sensor with a male oblong connector and 4-wire harness, so it should be matched to the exact downstream location listed for your vehicle. Confirm thread size, harness length, and sensor position on Audi, Volkswagen, or Porsche applications before replacement.

Quality Assurance

Bosch supplies this oxygen sensor as an OE-proven replacement backed by more than five decades of oxygen-sensor development. The design uses ceramic sensing elements, controlled heater operation, and heat-resistant materials to maintain consistent signal quality in demanding exhaust conditions.
