04L907807GK Audi NOx-Sensor

This sensor measures a physical property—could be temperature, pressure, speed, position, even light levels—and turns that into an electrical signal your car’s computer can understand. Basically, it’s an information gatherer. Different sensors measure different things, obviously, but that’s the core idea. It’s not doing anything mechanically; it’s just reporting back what’s happening. Think of it like this—your car’s computer is the brain, and the sensors are the nerves. This one specifically provides data that affects how various systems operate. Depending on what it senses, the computer might adjust engine timing, fuel delivery, transmission shifting, or even things like stability control. Without accurate input from this sensor, the computer can’t make the right decisions. It's part of a closed loop system; it reports, the computer reacts, and then it checks again. A failing sensor can cause all sorts of problems. You might notice a change in performance – maybe the engine doesn’t run as smoothly, the gas mileage drops, or a warning light comes on. Sometimes it's subtle, sometimes it’s pretty obvious. It can affect drivability significantly. Ignoring a bad sensor can sometimes lead to bigger, more expensive issues down the road, because the computer is making decisions with inaccurate information. If you’re getting a code related to this sensor, it’s definitely worth addressing. We carry a good selection of these, and you can also find them at places like Fixparts Online if you prefer to shop around. Replacing it usually isn't too difficult, but it depends on where it’s located in the vehicle. Reliable engineering: Sensor (MPN 04L907807GK) includes a 12-month warranty!
