Troubleshooting
Check Engine Light remains on after installation
Use an OBD-II scanner to clear the stored fault codes from the ECU after the new sensor is installed.
Difficulty removing the old sensor
Apply a penetrating oil to the sensor base and let it sit for several minutes, or run the engine briefly to warm the manifold and expand the metal.
Sensor wire is too long or short
Verify your specific vehicle chassis and engine code against the Walker fitment catalog, as some models may require different lead lengths.

Setup, Compatibility & Care
To install the Walker 350-34160, ensure the engine is completely cool to prevent burns and to make the sensor easier to remove. Always disconnect the negative battery terminal before starting. Use a dedicated oxygen sensor socket to prevent damaging the wiring or the sensor body. When threading the new sensor, apply a light coat of high-temperature anti-seize compound to the threads if it is not pre-applied, but ensure no compound touches the sensor tip. Ensure the harness is clipped away from hot exhaust manifolds to prevent melting. This sensor is compatible with various Audi, Seat, Skoda, and VW models. Always cross-reference your vehicle's specific OEM part number before purchase.
