Bosch Oxygen Sensor P/N:15386
Bosch 17100 oxygen sensor for the 2014-2018 Volkswagen Jetta 4-cylinder 1.8L, the 2015 Jetta 4-cylinder 2.0L and other vehicles measures the air-fuel ratio in the exhaust and passes it to the ECU. The ECU uses that reading for air-fuel mixture control, which supports fuel efficiency and reduced emissions.
A worn upstream sensor can bring on a check engine light, poor fuel economy or a rough idle. Those signs alone don't prove the sensor is at fault, since a vacuum leak is another common source. This listing is one sensor; the 2014-2018 Volkswagen Jetta 4-cylinder 1.8L takes one.
This sensor is listed for a wide range of Volkswagen, Audi and Porsche models, including the 2017-2018 Audi A4 4-cylinder 2.0L, and it is a Passat oxygen sensor for the 2014-2017 Volkswagen Passat 4-cylinder 1.8L.
