Bosch Oxygen Sensor P/N:15936
Bosch 18087 oxygen sensor for the 2012-2015 Audi A6 Quattro V6 3.0L and other vehicles sends air-fuel-ratio readings from the exhaust to the ECU. The ECU uses them to keep combustion stable and help reduce emissions.
An oxygen sensor that is wearing out can show up as a check engine light, a rough idle or lower fuel economy, though other faults produce the same signs. Before you replace this sensor, rule out damaged wiring or an exhaust leak, since either can skew the readings.
This sensor is listed for a wide range of Audi models, among them the 2012-2015 A6 Quattro V6 3.0L, the 2012-2015 A7 Quattro V6 3.0L and the 2013-2014 A8 Quattro V6 3.0L. This listing is one downstream sensor, and those Audis take two.
