AdBlue is a crucial component in modern diesel engines, playing a vital role in reducing harmful emissions. However, when it comes to the Land Rover Discovery Sport, you might encounter situations where AdBlue needs to be reset. This guide will provide you with a detailed understanding of AdBlue reset, why it’s necessary, and how to perform it safely and effectively.
Understanding AdBlue Reset and Its Importance
AdBlue, a solution of urea and deionized water, is injected into the exhaust system to convert harmful nitrogen oxides (NOx) into harmless nitrogen and water vapor. It’s a vital part of meeting stringent emission standards.
Why AdBlue Reset is Necessary:
- Low AdBlue Levels: As AdBlue is consumed, the system monitors its level. When the level falls below a certain threshold, a warning light will appear on the dashboard, indicating the need for refilling.
- Incorrect AdBlue Filling: In some cases, filling the AdBlue tank with the wrong type of solution or using contaminated AdBlue can trigger a system error requiring a reset.
- AdBlue System Malfunction: Issues like sensor failures, pump malfunctions, or software glitches can affect the AdBlue system’s performance, potentially necessitating a reset.
- After Replacing AdBlue Sensor: If the AdBlue sensor needs replacement, a reset is generally required to recalibrate the system.
