Walker Products Oxygen Sensor P/N:250-241219
Walker Products 250-25052 left oxygen sensor for the 2016 Volkswagen Touareg V6 3.0L and other vehicles measures the oxygen in the exhaust gas so combustion efficiency can be monitored.
A failing sensor can make the engine run poorly, raise fuel use or exhaust emissions, or turn on the malfunction indicator light. These signs alone do not prove the sensor is the problem, because a damaged wiring harness or connector can cause the same symptoms.
This sensor fits the 2016 Volkswagen Touareg V6 3.0L, the 2009-2010 Volkswagen Beetle 5-cylinder 2.5L and the 2008-2009 Audi A8 Quattro W12 6.0L.

With the engine off and cool, look at the sensor, wiring harness and connector for physical damage. Newer vehicles also store fault codes in the ECU that relate to the affected sensor.
What does the coating on this oxygen sensor protect?
The coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates in the exhaust gas. The electrodes carry a gas-permeable platinum layer.
