Bosch 17182 Oxygen Sensor - Upstream

Bosch Wideband O2 Sensor for OE Accuracy

Bosch 17182 is an Actual OE Oxygen Sensor built as a wideband air-fuel sensor for precise mixture feedback across the full lambda range. It is a specific-fit, heated replacement with a 5-wire harness and threaded mounting for direct service on select Audi and Volkswagen applications, including Audi A8 Quattro, Audi S8, Volkswagen Beetle, and Volkswagen Phaeton.

Key Features

• Wideband A/F oxygen sensor for continuous air-fuel ratio measurement
• Heated design for faster light-off and stable operation
• Specific-fit replacement with included wiring harness
• Blade terminals, oblong connector, male connector and terminal ends
• Threaded mounting with 18 mm thread size and 22 mm hex size
• Steel finish with metal housing for OE-style service replacement
• Bosch part number 17182 for direct catalog lookup

Product Details

Bosch’s Actual OE Oxygen Sensor line is based on the company’s long OE development history and wideband sensor technology used in modern engine management systems. This Bosch 17182 sensor uses a planar pump-cell wideband design to provide the ECU with detailed air-fuel data, helping maintain accurate fuel control under changing load and temperature conditions. It is a standard replacement part for upstream locations on select 2006 Volkswagen Phaeton, 2008-2009 Audi A8 Quattro, 2008-2009 Audi S8, and 2009-2010 Volkswagen Beetle applications. This part cross-references 1K0998262P for the same application.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn upstream sensor
• Rough idle or drivability issues tied to mixture control
• Reduced fuel economy caused by inaccurate exhaust feedback
• Higher emissions from delayed or inconsistent sensor response

Installation Notes and Tips

Verify the upstream sensor location, cylinder-bank application, connector style, and thread size before installation. This Bosch 17182 oxygen sensor is a specific-fit part with a 64.4-inch wiring harness length and 66.5-inch sealing-surface-to-connector length, so routing should match the original layout. Confirm the vehicle’s engine configuration on Audi A8 Quattro and Audi S8 applications, since fitment varies by cylinder group.

Quality Assurance

Bosch supplies this Actual OE Oxygen Sensor using OE-proven engineering, robust ceramic construction, and heater control tuned for reliable operation through thermal cycling. The Bosch 17182 is built to the same general standards expected from Bosch OE development for modern emission control systems.
