AdBlue Problems: Here’s What You Need to Know


As the world becomes more environmentally conscious, many industries seek ways to reduce their carbon footprint. One way the transportation industry does this is by using AdBlue, a liquid that helps reduce harmful emissions from diesel engines.

However, like any new technology or product, there are some AdBlue problems that you should know of. Fortunately, this article will discuss what AdBlue is, how it works, and some common problems that can arise when using it.

What Is AdBlue?

AdBlue is a mixture of water and urea used in diesel engines to minimise the production of nitrogen oxide (NOx) emissions. These emissions can lead to air pollution, adversely affecting human health and the environment.

This substance transforms harmful NOx emissions into harmless nitrogen and water vapour. It reacts with NOx in the catalytic converter, which breaks it down into nitrogen and water vapour. This process is referred to as Selective Catalytic Reduction (SCR).

Problems That Arise When Using Adblue


AdBlue is a delicate liquid that can easily become contaminated if it comes into contact with other substances, such as diesel fuel or oil. This can make AdBlue less effective, leading to increased NOx emissions and potential damage to the engine.

Hence, you must use high-quality AdBlue that meets the ISO 22241 standard. This standard guarantees that AdBlue is pure and does not contain pollutants. Additionally, store AdBlue appropriately since exposure to high temperatures and sunlight can cause it to deteriorate and lose effectiveness.

Incorrect Dosing

AdBlue dosage is a critical factor in reducing NOx emissions. Incorrect dosing can lead to increased emissions and potential damage to the engine.

To ensure correct dosing, use an AdBlue system that is calibrated and maintained correctly. Regular checks should be performed to ensure the system is functioning correctly and the correct amount of AdBlue is being injected into the exhaust system.

You should also use the appropriate AdBlue tank size for the vehicle and ensure the tank is kept topped up to prevent the engine from running without AdBlue, which can cause damage. For instance, if the AdBlue tank runs dry, the engine may go into a reduced power mode, and in severe cases, it may not start at all. 

Freezing at Low Temperatures

AdBlue tends to freeze at low temperatures, which can cause issues with dosing. Hence, storing AdBlue in a location not exposed to freezing temperatures is recommended. If the AdBlue does freeze, it can be thawed in a warm location or using a thawing agent. 

It is also important to note that using AdBlue that has been frozen and thawed may affect its quality and effectiveness, so it is best to avoid using it if possible. 

Ran Out of Adblue

There are times when you may run out of AdBlue. In this case, refilling the AdBlue tank as soon as possible is important to ensure the proper functioning of the vehicle’s emissions system. Driving without AdBlue can cause the vehicle to go into limp mode, which limits the engine’s power and speed.

Final Thoughts

AdBlue has become a necessary component for modern diesel engines, but it can also lead to various problems if not handled properly. From contamination to incorrect dispensing, the potential issues are numerous. However, these issues can be avoided by adhering to the manufacturers’ recommendations and guidelines and ensuring proper AdBlue storage, handling, and usage.
