Bosch 13842 oxygen sensor for the 1996 Volkswagen Passat 4-cylinder 2.0L, the 1996-2000 Passat V6 2.8L, the 1998-1999 Passat 4-cylinder 1.8L and other vehicles measures the air-fuel ratio in the exhaust and sends it to the ECU.
A check engine light, rough idle or higher fuel use can go with a worn oxygen sensor, but an exhaust leak or damaged wiring can cause them as well. With the engine off and cool, look the connector and wiring over for damage first. If the sensor is the cause, this one replaces it.
This sensor is listed for a wide range of Volkswagen and Audi models, including the 1997-2000 Audi A4 Quattro 4-cylinder 1.8L, the 1998-1999 A4 Quattro V6 2.8L and the 1999-2000 Volkswagen Eurovan V6 2.8L. This listing is one sensor, and depending on the engine a car takes one or two.
