How does AdBlue cause engine problems and how can you prevent this? 

Recently there has been a lot of controversy surrounding issues with AdBlue. Consumer organisation Testaankoop has even set up an online form where you can report (false) error messages caused by the AdBlue system. But what exactly is AdBlue and most importantly: how can you avoid these problems yourself? In this article we’ll tell you everything you need to know so you can continue to use AdBlue safely. 

AdBlue: an additive for modern diesel vehicles

AdBlue is added to the fuel of modern diesel vehicles equipped with Selective Catalytic Reduction (SCR) systems to reduce the emission of nitrogen oxides (NOx). When AdBlue is injected into the catalyst, it converts harmful NOx emissions into harmless nitrogen and water vapour. Its primary purpose is to reduce harmful emissions, which means AdBlue has a positive impact on the environment (Euro 6 emission standard). As an added bonus, AdBlue can also enhance engine performance. However, despite its many advantages, AdBlue does have some potential drawbacks. Don’t worry — There’s an easy solution for all of them.

Four common AdBlue issues

The first problem is the easiest to avoid: insufficient AdBlue levels. The Selective Catalytic Reduction (SCR) system can’t function properly when there isn’t enough of the additive in the system. Regularly checking the AdBlue level (or having it checked by a professional) is the easiest way to prevent this from happening. Some (French) models are experiencing problems with the automatic warning message for the AdBlue level, which is why it’s important to keep an eye on this.

The second possible issue is contaminated AdBlue, which can potentially damage or clog the catalytic converter. An additional additive, which we’ll discuss shortly, can easily solve this problem. 

The quality of the AdBlue additive is a potential third problem. It’s very important for the AdBlue to match the specifications of your engine. Using a low-quality product can potentially lead to serious engine malfunctions. If you consistently stick to the manufacturer’s recommendations, you’re good to go!

The fourth and final potential issue has everything to do with improper storage or exposure to extreme temperatures. Both of these could lead to changes in the composition of the AdBlue and reduce its effectiveness.

Better to be safe than…

…needing to replace or repair your diesel engine. Even just replacing the AdBlue tank comes with a price tag of over €1000, which is an unnecessarily expensive ordeal.

That’s why Xenum has developed Admax: an innovative additive that not only protects, but also enhances the performance of AdBlue.

Simply add Admax to the AdBlue reservoir to significantly improve the efficiency of AdBlue. The advanced formula prevents crystal formation in the Selective Catalytic Reduction (SCR) system and protects the injectors from contamination. Additionally, Admax helps to protect and condition AdBlue during extended storage periods.  

Admax offers the ideal solution to the issues we mentioned above. On top of that, it extends the lifespan of your Selective Catalytic Reduction (SCR) system, making Admax worth every penny.
