Walker Products Oxygen Sensor P/N:350-34340
Walker Products 350-35059 right oxygen sensor for the 2004 Volkswagen Touareg V10 4.9L measures the oxygen in the exhaust gas to track combustion efficiency. This Walker Products oxygen sensor is made for the upstream right position and gives the ECU the diagnostic feedback it requires.
A failing oxygen sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light. Before you replace the sensor, rule out physical damage to the wiring harness and connector, since damage there can also shorten a sensor's life.
This oxygen sensor fits the 2004 Volkswagen Touareg V10 4.9L. The 2004 Volkswagen Touareg V10 4.9L takes one sensor in this position, and the other side is ordered separately.

Does this Touareg oxygen sensor fit the 2004 Volkswagen Touareg V10 4.9L?
Yes. Walker Products 350-35059 is the upstream right oxygen sensor for the 2004 Volkswagen Touareg V10 4.9L, and the vehicle takes one in this position.
Is this oxygen sensor wide-band or narrow-band?
This oxygen sensor is a wide-band type. It measures the oxygen content of the exhaust gas to monitor the air-fuel ratio.
What are the electrodes in this oxygen sensor made of?
The electrodes have a gas-permeable platinum layer. A coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates.
What can a failing upstream oxygen sensor cause?
Signs can include the engine running poorly, higher fuel use or a lit malfunction indicator light. A shop can read stored fault codes and test the sensor.
Will a new oxygen sensor help fuel economy?
Walker Products 350-35059 measures exhaust oxygen to help fine-tune the air-fuel mixture, which supports fuel economy. If a failed sensor is behind higher fuel use, replacing it helps.
