Bosch 17100 Oxygen Sensor - Upstream

Bosch Actual OE Oxygen Sensor 17100

Bosch 17100 is an Actual OE wideband oxygen sensor built for precise air-fuel ratio measurement across the full lambda range. It is a specific-fit, heated sensor with a 5-wire blade terminal design and an included wiring harness for direct replacement on select Audi, Porsche, and Volkswagen applications.

Key Features

• Wideband A/F oxygen sensor for continuous, high-precision mixture feedback
• Heated design for faster light-off and stable operation during cold starts
• Specific-fit replacement with oblong male connector and 5 terminals
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Metal housing and robust ceramic sensor construction for OE-style durability
• Wiring harness included; harness length measures 23.8 in
• Overall length: 27.2 in; sealing surface to connector end: 26 in

Product Details

Bosch pioneered the wideband A/F oxygen sensor design used in modern engine management, and part number 17100 reflects that OE development history. This Bosch Actual OE Oxygen Sensor is engineered to deliver detailed exhaust feedback so the ECU can manage fuel delivery more accurately than with a traditional switching sensor. It is a direct-fit, upstream sensor for select Audi A4, A5, Q5, Q7, A8 Quattro, RS5, Porsche Macan, and Volkswagen Jetta, Beetle, and Passat applications. This part cross-references Bosch OE-style numbers 06K906262DA and 06L906262G for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn upstream sensor
• Poor fuel economy caused by inaccurate exhaust feedback
• Rough idle, hesitation, or drivability issues tied to mixture control
• Failed emissions testing due to sensor response problems
