Walker Products 350-35050 oxygen sensor for the 2013-2016 Audi A4 4-cylinder 1.8L and other vehicles reads the oxygen in the exhaust gas. This upstream wide-band sensor is made for its specific application and position, and it gives the ECU the diagnostic feedback it expects.
- Electrodes coated with a gas-permeable platinum layer
- Monitors exhaust gases and reduces pollutants
- Tracks the air-fuel ratio for combustion efficiency
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
Quick facts
- Part: Walker Products 350-35050 oxygen sensor
- Fits: the 2013-2016 Audi A4 4-cylinder 1.8L and other vehicles
- Position: Upstream
- Condition: New
A failing oxygen sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. If the sensor is the cause, this part replaces it. Before replacing it, look over the sensor, its wiring harness and its connector for physical damage, with the engine off and cool.
Fits
This oxygen sensor also fits the 2015-2018 Volkswagen Golf 4-cylinder 1.8L and the 2015-2019 Volkswagen Golf SportWagen 4-cylinder 1.8L, along with other vehicles. If your car is not named here, open the "Vehicles it fits" section and match your exact model and engine. Each of these cars takes one upstream sensor, and this listing is a single sensor.

Frequently Asked Questions
Is this Audi A4 oxygen sensor right for the 2013-2016 model with the 4-cylinder 1.8L?
Yes. Walker Products 350-35050 fits the 2013-2016 Audi A4 4-cylinder 1.8L, which takes one sensor in the upstream position.
Is this a VW Golf oxygen sensor for the 2015-2018 model with the 4-cylinder 1.8L?
Yes. This sensor fits the 2015-2018 Volkswagen Golf 4-cylinder 1.8L. For another car, open the "Vehicles it fits" section and match your exact model and engine.
What are the electrodes on the Walker Products 350-35050 made of?
The electrodes are coated with a gas-permeable platinum layer. A further coating protects their surfaces from contamination and erosion by combustion residue and particulates.
Is the Walker Products 350-35050 an upstream or a downstream oxygen sensor?
Walker Products 350-35050 is an upstream oxygen sensor. It is a wide-band type that measures combustion efficiency from the amount of oxygen in the exhaust gas.
What can a worn wide-band oxygen sensor do besides light up the dash?
A failing oxygen sensor can contribute to rough running, higher fuel consumption or more exhaust emissions. Newer vehicles may also store fault codes in the ECU, some of them tied to the sensor.
