  • Slow sensor response from an aging heated oxygen sensor

Installation Notes and Tips

Verify the exact position on your vehicle before ordering, since this part is used in multiple locations including front, rear, center, rear left, rear right, and center left applications. Confirm connector style, thread size, and overall length against the original sensor on your Volkswagen Passat, Audi A3, or Volkswagen GTI application.

Use the vehicle application tab and existing sensor routing to confirm fitment before installation. The included instruction sheet can help with basic replacement steps and connector identification.
