Detailed Description

Bosch 17192 is a wide band oxygen sensor engineered for accurate upstream exhaust feedback on 2015-2016 Audi A3 and 2015 Volkswagen Beetle, Golf, Golf SportWagen, Jetta, and Passat applications. As part of Bosch’s Actual OE Oxygen Sensor line, it reflects the company’s long OE development history and the planar pump-cell wideband design that became the standard for modern engine control. The sensor provides the ECU with detailed air-fuel ratio data across the full lambda range, helping maintain precise mixture control under changing load and temperature conditions.

For buyers searching for an upstream oxygen sensor for 2015 Audi A3 or a Bosch 17192 replacement for 2015 Volkswagen Golf, this part is built to match the listed fitment and connector style. It features a 22.6 in wiring harness length, 24.8 in sealing-surface-to-connector length, 26.0 in overall length, 22 mm hex size, and 18 mm thread diameter.

This part cross-references 03L906262Q for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings at the ECU
• Rough idle or drivability issues tied to upstream sensor feedback
• Reduced fuel economy from inaccurate mixture control
• Elevated emissions from delayed or unstable sensor response

Installation Notes and Tips

• Verify upstream location and connector match before installation.
• Inspect the harness routing and connector condition during replacement.
• Use the correct 18 mm thread size and 22 mm hex tool for service.
• Confirm the vehicle application by year, make, model, and position before ordering.
