Bosch Oxygen Sensor P/N:16155
Bosch 15160 oxygen sensor for the 1998-1999 Volkswagen Passat 4-cylinder 1.8L and other vehicles sends air-fuel-ratio measurements from the exhaust to the ECU. It is a switching-type sensor that helps the ECU hold stable combustion and reduce emissions.
A worn oxygen sensor can show up as a check engine light, higher fuel use or a rough idle. Before you replace this sensor, rule out an exhaust leak near it or damaged wiring, since either can feed the ECU a false reading.
It is listed for a wide range of Volkswagen and Audi models, including the 1999-2000 Volkswagen Eurovan V6 2.8L and the 1998-2000 Audi A4 Quattro 4-cylinder 1.8L.
