Bosch 17024 Oxygen Sensor - Downstream or Upstream

Bosch Wideband O2 Sensor for VW and Audi

Bosch 17024 is an Actual OE oxygen sensor built as a wideband air-fuel sensor for precise mixture feedback to the ECU. It is a heated, specific-fit replacement with a 5-wire harness, threaded mounting, and OE-style connector design for direct service on select Volkswagen and Audi applications.

Key Features

• Wide-band oxygen sensor type for continuous air-fuel ratio measurement across the full lambda range
• Heated design with optimized heater control for faster sensor activity after startup
• Specific-fit replacement with wiring harness included
• 5-wire configuration with blade terminals and oblong male connector
• Threaded 18 mm mounting with 22 mm hex size
• Robust metal housing for OE-style durability in high-heat exhaust locations
• Part number 17024 for easy identification during service

Product Details

Bosch 17024 is part of the Bosch Actual OE Oxygen Sensor line, which focuses on OE-proven sensor design for modern engine management systems. Bosch pioneered the wideband A/F oxygen sensor and the planar pump-cell architecture used in current low-emission control strategies. This sensor provides detailed feedback that helps the ECU manage fuel delivery more accurately than a traditional switching sensor, supporting stable operation during load changes, cold starts, and normal driving. It is a direct replacement for select Volkswagen Beetle, Golf, Jetta, Touareg, Passat, and Audi A3 models listed below.

This part cross-references 1K0998262AE for the same application.

Common Issues This Sensor Can Address

• Fault codes related to oxygen sensor response or air-fuel ratio monitoring
• Rough idle or inconsistent fuel control caused by inaccurate exhaust feedback
• Reduced fuel economy from a worn wideband sensor
• Emissions test failures tied to sensor degradation
• Delayed sensor activity after startup due to heater or aging-related performance loss

Installation Notes and Tips

Confirm the sensor position before ordering, since this Bosch 17024 application list includes both upstream and downstream locations. Match the connector shape, terminal count, thread size, and harness length to the original part before installation. Use proper oxygen sensor service tools on the 18 mm threaded sensor body, and inspect the exhaust bung and wiring routing for heat damage before final assembly.

Quality Assurance

Bosch backs this sensor with more than five decades of OE development in engine management and emissions control. The Bosch Actual OE Oxygen Sensor line is built to OE specifications for accurate signal delivery, reliable heater performance, and consistent service life in demanding exhaust environments.
