Hella Oxygen Sensor 009166821

Restore accurate air-fuel feedback with this Hella oxygen sensor, part number 009166821. It is a 6-pin regulating probe mounted in front of the catalyst with a 1500 mm cable, built for direct replacement on select Audi and Volkswagen applications.

Key Features

  • Hella oxygen sensor / lambda sensor, regulating probe style
  • 6-pole connector for OE-style electrical connection
  • 1500 mm cable length for factory routing
  • Installs in front of the catalytic converter
  • Compatible with select Audi A4, Audi TT, Volkswagen Golf, and Volkswagen Jetta applications
  • Part number 009166821 for accurate catalog matching

Product Details

Hella 009166821 is an upstream oxygen sensor used to monitor exhaust oxygen content before the catalyst so the engine control module can adjust fuel delivery. This matters for drivability, emissions performance, and fuel control on vehicles such as the Audi A4, Audi TT, Volkswagen Golf, and Volkswagen Jetta. The 6-pin design and 1500 mm lead length support OE-style replacement where the original sensor uses the same configuration.

This part cross-references Dorman - HELP 81528 and Four Seasons 75351 for the same application.

What It Helps Address

  • Check engine light related to oxygen sensor performance
  • Incorrect fuel trim readings
  • Rough idle or hesitation tied to air-fuel control
  • Failed emissions inspection from a faulty upstream sensor
  • Poor fuel economy caused by inaccurate exhaust feedback

Installation Notes

Verify connector style, pole count, and sensor location before installation. This sensor is specified for the exhaust system in front of the catalyst, and fitment includes front or front-right applications depending on vehicle. Confirm routing length and mounting position on the vehicle before replacing the original unit.
