Bosch 17480 Oxygen Sensor - Upstream or Upstream Left

Bosch Wideband OE Oxygen Sensor for Volkswagen and Audi

Bosch 17480 is an Actual OE Oxygen Sensor built as a wideband air-fuel ratio sensor for precise engine management. It delivers continuous lambda measurement, fast heater response, and stable readings for vehicles that rely on accurate upstream feedback.

Compatible With select Volkswagen Passat, Beetle, Golf, Jetta, Eos, R32, Phaeton, Audi A3 Quattro, A4, A4 Quattro, TT Quattro, and Bentley Continental applications, Bosch 17480 is a direct-fit replacement for the original sensor on listed vehicles.

Key Features

• Wideband A/F oxygen sensor with continuous air-fuel ratio measurement
• Heated design for faster light-off and improved cold-start response
• Specific-fit sensor with 5-wire harness and included wiring harness
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Oblong male connector with blade terminals and 6 terminal positions
• Robust metal housing for OE-style durability in high-heat exhaust locations
• Bosch Actual OE Oxygen Sensor line for OE-proven replacement performance

Product Details

Bosch 17480 uses wideband sensor technology to provide the ECU with more detailed air-fuel data than a traditional switching sensor. That added precision helps the engine control system maintain the correct mixture across changing load and temperature conditions, which is important for drivability, fuel economy, and emissions control. Bosch pioneered the planar pump-cell wideband design used in modern engine management, and this sensor reflects that OE development background.

This part cross-references 1K0998262N and 06A906262BK for the same application. The Bosch 17480 part number is commonly searched for upstream oxygen sensor replacement on Volkswagen and Audi platforms, including Volkswagen Jetta upstream oxygen sensor and Audi A4 Quattro upstream oxygen sensor applications.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn upstream sensor
• Rough idle, hesitation, or inconsistent throttle response
• Reduced fuel efficiency caused by inaccurate exhaust feedback
• Emissions test failures tied to sensor response or signal quality

Installation Notes

Verify the connector shape, wire count, and upstream position before installation. This sensor is a specific-fit, threaded replacement with an overall length of 48.6 in and a sealing-surface-to-connector length of 47.4 in. Confirm the vehicle uses the listed brown-connector or upstream configuration where noted, and inspect the exhaust bung threads before tightening to specification.
