Adblue Problems
Common AdBlue Problems
-
Injector failures – usually due to clogging
-
Pump failure – faults can be caused by contamination, poor quality adblue or crystalisation.
-
Adblue Tank level sensor – these can stick , or the vehicles engine management can misread the level.
-
NOX sensor failure – these sensors often fail – usually on Mercedes, Ford and VW/Audi
These problems can be fixed, but there is often a waiting list for parts and the inevitable delay of getting booked into a workshop.

Common AdBlue Problems
1. Crystallization and Clogging
One of the most frequent issues with AdBlue is crystallization. When exposed to air or not properly managed, AdBlue can crystallize, leading to clogged injectors and filters. This blockage can cause the system to malfunction, leading to increased emissions and potential engine damage.
Solution: Regular maintenance is crucial. Ensure that the AdBlue tank is sealed properly to prevent exposure to air. If crystallization occurs, cleaning the injectors and filters with specialized solutions can resolve the issue.
2. Contamination
AdBlue must remain pure to function correctly. Contaminants such as dirt, oil, or even improper handling can compromise its quality, leading to system failures. Contaminated AdBlue can damage the SCR (Selective Catalytic Reduction) system, resulting in costly repairs.
Solution: Always use high-quality AdBlue from reputable suppliers. Avoid using makeshift funnels or containers that might introduce contaminants. Regularly check and clean the AdBlue tank to ensure purity.
3. Freezing in Cold Weather
AdBlue has a freezing point of around -11°C (12.2°F). In colder climates, this can pose a significant problem as frozen AdBlue cannot be injected into the exhaust system, leading to system errors and potential engine shutdowns.
Solution: Modern vehicles are typically equipped with heated AdBlue tanks to prevent freezing. Ensure this heating system is functioning correctly. For older models, consider using additives specifically designed to lower the freezing point of AdBlue.
4. Incorrect AdBlue Levels
Maintaining the correct AdBlue level is essential for the system to function properly. Low levels can trigger warning lights and may eventually lead to engine derating, where the engine power is reduced to prevent damage.
Solution: Regularly monitor the AdBlue levels and top up as necessary. Most vehicles have a dashboard indicator to alert you when levels are low. Ignoring these warnings can result in engine performance issues.
5. AdBlue Pump Failures
The AdBlue pump is responsible for delivering the fluid to the exhaust system. Mechanical or electrical failures in this pump can disrupt the entire AdBlue system, leading to increased emissions and potential legal issues.
Solution: Regular inspections and maintenance can help identify pump issues before they become critical. Replacing faulty pumps promptly ensures the AdBlue system remains operational.
Preventive Measures
To minimize AdBlue-related issues, follow these preventive measures:
- Regular Maintenance: Schedule regular checks for the entire AdBlue system, including injectors, filters, and the tank.
- Quality Assurance: Use only high-quality AdBlue from trusted suppliers to avoid contamination and ensure optimal performance.
- Proper Storage: Store AdBlue in a cool, dry place to prevent degradation and crystallization.
- System Monitoring: Keep an eye on dashboard alerts and address any issues immediately to prevent long-term damage.
Conclusion
While AdBlue is essential for reducing diesel emissions, it can present several challenges. Understanding these common problems and knowing how to address them can help maintain your vehicle’s performance and compliance with environmental regulations. Regular maintenance, quality assurance, and proactive monitoring are key to preventing and resolving AdBlue-related issues. By taking these steps, you can ensure that your diesel engine runs smoothly and efficiently, contributing to a cleaner environment.
