Audi Knock Sensor
If your Audi knock sensor has failed, you'll need to replace it right away, as without it, your engine lacks an important protection against damage to some of the more sensitive, as well as expensive, parts of your combustion system. What the Audi knock sensor does is send a signal to the main computer of your vehicle when it detects the vibration that indicated that the fuel has detonated instead of burned. When the fuel detonates, or explodes, rather than burns, it often is happening too soon and outside of the correct combustion area, which means that, if left unchecked, serious damage to such parts as your pistons can occur, which are much more difficult and costly to replace than is your Audi knock sensor. When the main computer receives the signal from your Audi knock sensor that the timing of the combustion needs to be adjusted, it will make the appropriate change and, if needed, signal the need for an adjustment in the air-to-fuel ratio. As with any part that has to do with the combustion process, a malfunctioning or completely failed Audi knock sensor can have a negative effect on fuel economy, and cause you to pay even more at the pump than you already do.
