What Is the AdBlue Warning Light and What Does It Mean?
AdBlue Warning Light is an indicator on the dashboard of modern diesel vehicles that is designed to alert drivers when the vehicle’s AdBlue tank is running low. AdBlue is a liquid solution made from urea and de-ionized water that helps reduce harmful emissions from diesel exhaust gases. When the AdBlue Warning Light illuminates, it indicates that the vehicle’s AdBlue tank needs to be refilled in order to continue operating. Failure to refill the tank can result in reduced engine performance and increased emissions.
Introduction
AdBlue is an aqueous urea solution used in automotive exhaust systems to reduce the amount of harmful pollutants emitted from diesel engines. The purpose of the AdBlue warning light is to alert the driver when there is a malfunction in the system, or when the AdBlue fluid level is low. This warning light helps to ensure that the vehicle remains clean and free of pollutants that can be damaging to both people and the environment.
