Audi A4 Replacement Air Fuel Ratio Sensor Information


The air fuel ratio sensor affects the mix of oxygen and gasoline sent to your Audi's engine. When it fails, you will usually see a "check engine" light, and your engine might receive a lean or rich air/fuel mixture.

A faulty air fuel ratio sensor can significantly affect the performance of your A4's engine. You may notice less power or worse gas mileage, and your engine might stumble during acceleration. Your vehicle's exhaust system will also experience extra stress, and you may have trouble passing any state-mandated vehicle emissions tests. Ideally, you should treat a failed air/fuel ratio sensor as soon as you can to avoid large repair bills. Parts Geek has replacement air fuel ratio sensors to keep your engine in great working condition. Our parts are designed to OEM specifications and will allow your Audi A4 to maintain a perfect fuel mixture.
