Extended Product Information
FAQs
What is the primary function of an oxygen sensor?
An oxygen sensor measures the amount of unburned oxygen in the exhaust gases. This information is sent to the engine control unit (ECU) to help optimize the fuel-air mixture for efficient combustion and reduced emissions.
How do I know if my oxygen sensor needs replacement?
Common signs include a glowing check engine light, decreased fuel economy, rough idling, poor acceleration, and failed emissions tests.
What does '4 Circuits' mean for this sensor?
A 4-circuit oxygen sensor typically includes a heating element and the signal element, each with its own ground. This provides faster response times and more accurate readings compared to older 1 or 2-wire sensors.
What OEM numbers does this sensor cross-reference?
This WALKER 350-34788 oxygen sensor is a replacement for OEM numbers 06K906262E and 06K906262AC.
What is the warranty period for this part?
Information regarding the specific warranty period and any return requirements (like returning the old product for a voucher) should be confirmed with the retailer at the time of purchase.
Can I install this myself?
While possible for experienced DIYers, installation often requires specialized tools and knowledge of exhaust systems and engine electronics. Professional installation by a qualified mechanic is recommended.
What is the length of the sensor cable?
The length of the cable for this specific sensor is 775mm.
Troubleshooting
Check Engine Light remains on after replacement
Ensure the sensor was correctly installed and the electrical connector is securely fastened. Clear the diagnostic trouble codes (DTCs) with a scan tool and verify the correct part number was used for your vehicle. A vacuum leak or other exhaust system issue could also trigger the light.
Poor engine performance or rough idle
Verify the oxygen sensor is the correct part for your vehicle and that it was installed properly. Check for exhaust leaks, as these can provide false readings. Inspect other engine components that could affect performance, such as spark plugs or mass airflow sensor.
Reduced fuel economy
Confirm the oxygen sensor is functioning correctly and that the vehicle's computer is receiving accurate data. Ensure there are no exhaust leaks and that other maintenance items (like air filter, tire pressure) are up to date.

Setup, Compatibility & Care
Compatibility: This oxygen sensor is designed to fit specific Audi A1, Lamborghini, Seat, Skoda, and VW models. Always verify compatibility with your vehicle's make, model, and year, and compare with OEM part numbers (06K906262E, 06K906262AC) before purchase.
Installation: Installation should be performed by a qualified mechanic. The sensor typically threads into the exhaust system. Ensure the area is cool before working. A specialized oxygen sensor socket wrench is often required. Always disconnect the vehicle's battery before starting any electrical component replacement.
Care: Oxygen sensors are sensitive components. Avoid exposing the sensor tip to excessive contaminants or physical damage during installation. No specific maintenance is required after installation; its performance is dependent on the vehicle's exhaust system condition.
