What Causes a Low AdBlue Warning Light and How to Fix it

AvatarByCarl Frisch

Low AdBlue Warning Light is a feature on some diesel-powered vehicles that alerts the driver when the AdBlue fluid level is low. AdBlue is a fluid used in some diesel engines to reduce emissions of nitrogen oxide (NOx) from the exhaust. When this light comes on, it is important to top up the AdBlue as soon as possible in order to maintain engine performance and fuel economy. If the level of AdBlue drops too low, the engine will eventually go into limp home mode, where it will operate at reduced power until refilled.

What is AdBlue?

AdBlue is a liquid solution made up of a combination of urea and deionized water, which is used in some diesel vehicles to reduce harmful emissions. It is injected into the exhaust system to help reduce nitrogen oxide (NOx) pollution that contributes to air pollution. AdBlue plays an important role in meeting environmental standards, as its use results in fewer harmful pollutants being released into the atmosphere. The AdBlue system works by converting NOx into nitrogen and water vapour, which are much less damaging to the environment.

What Does the AdBlue Warning Light Indicate?

The AdBlue warning light indicates that there is a problem with the AdBlue system or that it needs to be serviced or refilled. This could be due to a faulty component or low levels of fluid in the tank. It’s important to have your vehicle checked as soon as possible if you see this warning light, as continuing to drive with an empty or malfunctioning AdBlue tank can cause damage to your engine.

What Should I Do If The AdBlue Warning Light Comes On?

If the AdBlue warning light comes on, you should stop driving your vehicle immediately and check the level of fluid in the tank. If it’s empty, you should top it up using an approved refill station or take your car to a mechanic for servicing. If there is still fluid in the tank and you’re not sure what caused the warning light, it’s best to take your car to a qualified mechanic for further inspection and repair.

Resetting And Clearing LowAd Blue Warning Lights

If you have topped up your vehicle’s AdBlue tank and are still seeing a low-level warning light, you may need to reset or clear it from your dashboard display. This can usually be done by switching off your engine and then restarting it again after a few seconds, which will reset all systems including the low-level warning lights associated with AdBlue systems. Alternatively, some vehicles allow drivers to manually reset these lights using their dashboard display interface; however this should only be done if you are confident about carrying out this procedure yourself.

Options For Resetting And Clearing LowAd Blue Warning Lights

Depending on your vehicle model, there are different options available for resetting and clearing low-level AdBlue warnings lights from your dashboard display.
