Modern diesel engines rely heavily on the AdBlue system to reduce harmful emissions and meet stringent environmental standards. However, like any system, it requires proper maintenance. Over time, your AdBlue system can become clogged or less efficient, leading to issues that may affect both performance and emissions. 

Here are five common warning signs that your AdBlue system may need cleaning—and how Wynn’s AdBlue additives can help. 

 

  1. Dashboard Warning Lights

One of the clearest signs that something is wrong with your AdBlue system is the appearance of warning lights on your dashboard. Most modern diesel vehicles are equipped with sensors that monitor the SCR (Selective Catalytic Reduction) system and will alert you if there is a problem. If you see an AdBlue-related warning, it could be a sign that the system is clogged or malfunctioning due to crystallisation or contamination. 

How Wynn’s Can Help: Wynn’s AdProtect prevents crystallisation from occurring and removes contaminants, helping to restore correct flow and function to the SCR system. Regular use prevents future issues and keeps the system clean. 

 

  1. Increased Exhaust Smoke

AdBlue systems are designed to reduce emissions, so if you notice increased exhaust smoke, particularly white or grey smoke, it could indicate that the system isn’t working properly. This is often a sign that the injectors are clogged, preventing the AdBlue from mixing correctly with the exhaust gases. 

How Wynn’s Can Help: Wynn’s AdProtect helps to prevent the formation of deposits that could be blocking the injectors, improving the flow of AdBlue and restoring proper emissions control. 

 

  1. Failed Emissions Test

If your vehicle fails an emissions test, it could be due to a malfunctioning AdBlue system. When the system isn’t working as it should, your vehicle may produce higher levels of nitrogen oxides (NOx), which can lead to failure in regulatory checks. 

How Wynn’s Can Help: By keeping your AdBlue system clean and free of crystallisation, Wynn’s AdProtect ensures that your SCR system is functioning at its best, helping your vehicle meet emissions standards. 

 

  1. Reduced Engine Performance

A faulty AdBlue system can impact your engine’s performance. You might notice reduced power or poor fuel efficiency, especially under heavy loads. This happens because the SCR system isn’t effectively controlling emissions, which can affect the engine’s overall efficiency. 

How Wynn’s Can Help: Wynn’s AdProtect additive ensures that the AdBlue system remains free from blockages, enabling the engine to perform at its best.  

 

  1. Crystallised Deposits Around the Injector

If you check under the hood and notice crystallised urea deposits around the AdBlue injector, this is a clear sign that your system is suffering from crystallisation. Left unchecked, these deposits can block the system, leading to injector failure or damage. 

How Wynn’s Can Help: Wynn’s Ad-Protect is specifically formulated to prevent new crystals from forming. Using it regularly will protect your system and ensure smooth operation.

 

Conclusion: 

If you notice any of these warning signs, your AdBlue system could benefit from a thorough clean. Wynn’s AdProtect offers an easy, effective way to solve these issues and prevent further damage. By using Wynn’s regularly, you can keep your vehicle running smoothly, control emissions and avoid costly repairs.
