Questions about these listings

Which model years are named in the listings for Audi A5 oxygen sensors?

7 listing titles give model years from 2006 to 2018. Check your car’s year against the fitment details in each listing.

Which positions are named in the listings for Audi A5 oxygen sensors?

The titles name downstream (6 listings) and upstream (6). Order for the position on your car, as stated in the title or the seller’s fitment details.

Which part numbers appear in more than one listing for Audi A5 oxygen sensors?

234-5019 appears in more than one title. Compare the number on your old part with the listing before you buy.

How do I check fitment before buying Audi A5 oxygen sensors?

Find which sensor has failed. Upstream sensors sit before the catalytic converter and control fuelling; downstream sensors sit after it and monitor the converter. A fault code that names the bank and sensor number identifies the position. Some engines use a wideband (air-fuel ratio) sensor upstream. It is not interchangeable with an ordinary oxygen sensor, so match the type as well as the position.

Check compatibility before buying

These listings were found using Audi A5 oxygen sensors search terms. A search match does not establish fitment. Compare the part number, vehicle year, generation and engine with the seller's compatibility details. Confirm delivery, returns and the final price on eBay before ordering.

Match the oxygen sensor to its exact position

  • Find which sensor has failed. Upstream sensors sit before the catalytic converter and control fuelling; downstream sensors sit after it and monitor the converter. A fault code that names the bank and sensor number identifies the position.
  • Some engines use a wideband (air-fuel ratio) sensor upstream. It is not interchangeable with an ordinary oxygen sensor, so match the type as well as the position.
  • Compare the part number, connector and wire length with your old sensor or a sensor catalogue. A listing that names several models, or a 4-sensor kit, may not match the sensor you need.

Reference: NTK guide to oxygen (lambda) sensor types. Use the catalogue’s correct regional application.
